Abstract

High Resolution Gamma-ray Spectroscopy (HRGS) and Total Absorption Gamma-ray Spectroscopy (TAGS) techniques of beta decay study and facilities for such techniques at VECC, Kolkata have been described. The preliminary results of the HRGS experiment performed at VECC to study the beta decay of 126Sb, an important nucleus for the reactor decay heat estimation, are presented. The observation of a 928-keV gamma ray confirmed the 2703.6 keV state in 126Te. The half-lives of both the beta-decaying states in 126Sb could be uniquely measured in this work. The results are useful for future TAGS measurements of the 126Sb beta decay.
