Description
The natural uranium targets are bombarded by 18O(60 MeV/u) ions, and the heavy neutron-rich isotope 237Th is produced through the multi-nucleon transfer reaction. A relatively fast radiochemical procedure is used to separate thorium from the uranium and complex reaction products mixture. The thorium fractions chemically separated are studied by off-line γ-ray spectroscopy using a HPGe detector coupled to a 4096 channel pulse-height analyzer. The growth-decay curve of 853.7 keV γ-ray from 237Pa (237Th daughter) are analyzed and the half-life of 237Th is determined to be 4.69 +- 0.60 min
