Independent Verification of Element 114 Production in the Ca 48 + Pu 242 Reaction
Description
Independent verification of the production of element 114 in the reaction of 244-MeV Ca48 with Pu242 is presented. Two chains of time- and position-correlated decays have been assigned to 128614 and 128714. The observed decay modes, half-lives, and decay energies agree with published results. The measured cross sections at a center-of-target energy of 244 MeV for the Pu242(Ca48,3–4n)1287,28614 reactions were 1.4−1.2+3.2 pb each, which are lower than the reported values.
