Abstract
132Te was produced via the 232Th (, fission ) reaction at the
Variable Energy Cyclotron , Calcutta. 132Te was separated
in carrier-free form from the fission products by radiochemical
separation and the half-lives for the 50 keV and 162 keV states
of 132I were determined to be 2.94
0.11 ns and 0.55
0.04 ns
respectively. The present results differ significantly from the
previously reported half-lives of 7.14 ns and 3.57 ns for the 50
keV and 162 keV states respectively.
