Independent verification of the production of element 114 in the reaction of 244-MeV ⁴⁸Ca with ²⁴²Pu is presented. Two chains of time- and position-correlated decays have been assigned to ²⁸⁶114 and ²⁸⁷114. 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 ²⁴²Pu(⁴⁸Ca,3–4n)²⁸⁷,²⁸⁶114 reactions were 1.4(+3.2, -1.2) pb each, which are lower than the reported values.
