Abstract
132Te was produced via the 232Th ($\alpha$, 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$\pm$0.11 ns and 0.55$\pm$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.
