Abstract
A new nuclear reaction for the production of 240Am was experimentally investigated. Targets of 150 – 500 μg/cm2242Pu on 2 μm Ti were produced through molecular deposition. Five irradiations, in which 242Pu, natTi, and natNi targets were jointly activated with protons from the Lawrence Berkeley National Laboratory 88-Inch Cyclotron produced 240Am, 48V, and 57Ni, respectively. The radioactive decay of these nuclides was monitored using high-purity Ge gamma ray detectors in the weeks following irradiation. A maximum 242Pu(p, 3n)240Am nuclear reaction cross section was measured to be 45 ± 13 mb with 23 MeV protons. While this value is lower than theoretical predictions, it is high enough to be the most viable nuclear reaction for the large-scale production of 240Am.
