Decay of 5.8-min Pmm140 and 10-sec Pmg140 to levels of Nd140

Published

Journal Article

The nuclear level structure of Nd140 has been investigated by studying the decay of 5.8-min Pmm140 and 10-sec Pmg140 with Ge(Li) γ-ray detectors. Sources were produced via the Pr141(He3, 4n)) reaction. The study of Pmg140 decay utilized a helium-jet recoil transport system. Fourteen γ rays were assigned Pmm140 decay and nine were attributed to Pmg140 decay. Decay schemes of Pmm140 and Pmg140 were constructed. Evidence for the low-spin members of the two-phonon triplet in Nd140 is also presented. RADIOACTIVITY Pmm+g140 [from Pr141(He3, 4n)]; measured Eγ, Iγ, γ-γ coin; t12; deduced Nd140 levels, J, π.
