After more than half a century of research and leadership at Berkeley Lab and the University of California at Berkeley, University of Mississippi chemical engineering alumnus Joseph Cerny (ChE 57) has retired.

The former head of the Nuclear Science Division and associate laboratory director at Berkeley Lab, professor of chemistry and former chemistry department chair, graduate division dean, provost and vice chancellor for research, Cerny left with another singular honor to add to a long list: the Berkeley Citation, awarded to those “whose attainments significantly exceed the standards of excellence in their fields” and whose contributions are “above and beyond the call of duty.”

Cerny reflected upon how he came to Ole Miss.

“Even though my parents were from Illinois and Kansas, my father was offered a faculty position in the Ole Miss business school,” Cerny said. “He accepted the job and we moved to Oxford in 1946, where I entered the sixth grade.”

As he finished high school, Cerny decided that he wanted to become a chemical engineer. That decision is what prompted him to enter the university’s School of Engineering.

“I had many classes with Frank Anderson, who was a great teacher,” Cerny said. “Other professors I remember as extremely demanding were C.N. Jones and Samuel Clark.”

Born at the height of the Great Depression, Cerny got his bachelor’s degree from UM with support from the ROTC program. During 1957-58, he attended the University of Manchester in England on a Fulbright Scholarship.

Cerny earned his doctorate in nuclear chemistry from UC Berkeley in 1961 and immediately started work as an assistant professor at the university, simultaneously joining the Nuclear Science Division (then the Nuclear Chemistry Division) at Berkeley Lab (then the Radiation Laboratory, or Rad Lab).

Shortly after the East German government began building the Berlin Wall, Cerny was on active duty as a first lieutenant in the U.S. Army. For most of the next 16 months, he was in New Jersey evaluating techniques for studying explosive detonations.

Once back at Berkeley, Cerny wasted no time catching up with nuclear science.

“Russian theorists had suggested some interesting ideas about experiments that could be done to study light nuclei very far from stability,” Cerny said. These were isotopes of elements like carbon whose nuclei had more protons than neutrons; most carbon is stable carbon-12, with six protons and six neutrons.

“For example, we wanted to know the lightest carbon nucleus that could hold together on the order of a hundred milliseconds.”

Cerny had a stellar new instrument to work with. His graduate work had been done with Ernest Lawrence’s 60-inch cyclotron, still operating on campus, but upon his return from the Army in 1963, the Rad Lab’s 88-Inch Cyclotron was up and running. It would be pivotal in Cerny’s research throughout his career.

Using state-of-the-art detectors and electronics developed by Fred Goulding and Don Landis at the lab, Cerny found the answer to the carbon stability question – carbon-9, with six protons and three neutrons, has a half-life of 126 thousandths of a second, whereas the lighter carbon-8 lasts only about 100 septillionths of a second – “a huge dividing line,” he said.

Cerny continued experiments on very proton-rich nuclei while on sabbatical at Oxford University in 1969-70, using a heavy-ion cyclotron at the Harwell Laboratory. He completed these studies at the 88-Inch. The result was the discovery of a new radioactive decay mode, direct proton radioactivity – the first mode of single-step radioactive transmutation to be discovered since alpha decay, beta decay and spontaneous fission.

Cerny received the Ernest Orlando Lawrence Memorial Award of the Atomic Energy Commission (predecessor of the U.S. Department of Energy) in 1974, for his “discovery of proton emission as a mode of radioactive decay, for investigation of the limits of nuclear stability of a number of light elements” – and, significantly – “for ingenious instruments that made these discoveries possible.”

In 1975, Cerny became chair of the UC Berkeley Department of Chemistry. One of his major acts was a first for the department: the appointment of a woman, Judith P. Klinman, as a tenured associate professor of bioorganic and biophysical chemistry. In 1979, Cerny was appointed head of the Nuclear Science Division and an associate lab director at Berkeley Lab, a time when the lab was operating three national accelerator facilities: the 88-Inch Cyclotron, SuperHilac and Bevalac, with a distinct taste for heavy-ion physics.

Cerny and his group continued research on radioactive decay modes, adding another first: beta-delayed two-proton emission, which had been predicted by Russian theorist V. Gol’danskii. Among other honors, Cerny received the American Chemical Society’s Award in Nuclear Chemistry for work leading to the discovery of “two new modes of radioactive decay: proton emission and beta-delayed two-proton emission.”

In 1985, Cerny was appointed dean of UC Berkeley’s Graduate Division, serving in that post until 2000. From 1986 to 1994, he also was provost for research, and from 1994 to 2000 was the university’s vice chancellor for research. And in 1990, Cerny additionally became a nuclear physicist, when the University of Jyväskylä in Finland awarded him an honorary doctorate in physics.

At a festschrift on his 60th birthday in 1996, Cerny presented a proposal for equipping the 88-Inch Cyclotron to handle radioactive beams of light ions. Radioactive isotopes of carbon, nitrogen and oxygen would be made by the cyclotron of the Berkeley Isotope Facility in Building 56, part of the imaging facilities of the Life Sciences Division. The radioactive ions would be transported 350 feet through a capillary down the steep slope of Blackberry Canyon to the 88-Inch.

Dubbed BEARS, for Berkeley Experiments with Accelerated Radioactive Species, the transport system was in operation just three years later, enabling the 88-Inch Cyclotron to produce a world record beam of radioactive carbon-11. That isotope’s 20-minute half-life was easily long enough, once it was created, to mix it with oxygen to make carbon dioxide and send the gas through the pipeline to the 88-Inch, where it was trapped and fed into an ion source at the cyclotron.

Cerny’s research, teaching and service work for DOE, NSF and the UC system are continuing from his base in Berkeley, where he and his family are longtime residents. It’s not unlikely that Cerny will be seen around the 88-Inch, a mainstay of his work since his Berkeley beginnings, for many days to come.

Cerny was married to the late Susan Cerny. He is the father of two sons: Keith, who is the general director of the Dallas (Texas) Opera Company, and Mark, a senior video game consultant with Sony Entertainment.

Cerny’s favorite leisure activities include hiking and worldwide travel.
