The intro of their paper reads: Note on the Transmutation Function for Deuterons J. R. OPPENHEIMER AND M. PHILLIPS, University of California, Berkeley (Received July 1, 1935) W'e consider the eRect of the finite size and ready polarizability of the deuteron on the probability of transinutations involving the capture of the neutron. These have as a consequence that the Coulomb repulsion of the nucleus is less effective than for alpha-particles or protons, and that the corresponding transmutation functions increase less rapidly with deuteron energy. W'e treat the collision by the adiabatic approximation and obtain quantitative results for this energy dependence which are in good agreement with experiment.

Oppenheimer arrived in Berkeley in 1929 to take a position as an assistant professor, in a special arrangement that also saw him teaching at Caltech. His first doctoral student at Berkeley was Melba Newell Phillips.
Together they discovered the Oppenheimer-Phillips process, where a passing deuteron is polarized by the electrostatic field of a nucleus. The deuteron’s proton is repelled, allowing the nucleus to capture the neutron and form a heavier isotope.
