Lifetime measurement in Te-124

摘要

Lifetimes of nuclear levels in Te-124 have been measured by the gamma-ray induced Doppler broadening (GRID) technique using the GAMS4 crystal spectrometer at the Institut Laue Langevin, Grenoble. The new experimental data allow the determination of absolute transition rates. The results show that the structure of Te-124 is best described by a configuration mixing calculation in the framework of the IBM-2. Precise gamma-ray measurements confirm a 2(+)-3(+) level doublet at 2039 keV with a spacing of 129 eV, (C) 2000 Elsevier Science B.V. All rights reserved. [References: 29]
