Abstract

In a series of Kr bombardments of Mo the new isotopes Pt and Pt were identified via their α-decay properties. The α-decay energies and half-lives of these two nuclides are as follows. (1) Pt, Eα = 7110(15) keV, T = 0.3(1) ms, and (2) Pt, Eα = 6988(10) keV, T = 0.7(2) ms. Also, the half-life of Pt, which was previously unknown, was determined to be 2.0(4) ms. In a separate but concurrent experiment involving Kr + Ru reactions, Pt was made and a half-life of 14.7(5) ms was measured for it; the one published value is 6 ms. Results for Os contained in the same data sets were also analyzed and by using mother-daughter correlations, the α branches of Os were established to be near 100%.
