Abstract

The level structure of 202Po was studied using the 195Pt(12C, 5n) reaction at a beam energy of 83 MeV. Improved lifetime measurements have been performed for the 8+ and 11− isomeric states by the decay slope method using high-purity germanium clover detectors. The half-lives of these isomeric states were found to be T1/2(8+)=114±5 ns and T1/2(11−)= 83±6 ns. The variation of the reduced transition probabilities with neutron and proton number in the decay of these proton-dominated isomeric states is discussed. © 2024 Jagiellonian University.
