FIRST RESULTS OF DECAY HEAT MEASUREMENTS WITH MTAS AT THE HRIBF

摘要

Total Absorption Spectrometers (TAS) capable of detecting most of the gamma transitions occurring during the decay process are perfect tools for establishing a true beta feeding pattern. TAS-aided experiments are particularly important for neutron-rich nuclei, where the beta strength is highly distributed over many final states. Knowledge of the correct beta feeding pattern is important for the analysis of the structure of parent and daughter activities as well as for the determination of the decay heat released by fission products during nuclear fuel cycle.
