Levels in154Eu populated by thermal neutron capture

  • Published:
Zeitschrift für Physik A Atoms and Nuclei

Abstract

The level scheme of154Eu has been investigated by means of thermal neutron captureγ-rays and conversion electrons. The high energyγ-ray spectrum from thermal neutron capture in enriched153Eu has been studied in the energy range of 5700 to 6500 keV. Low energyγ radiation has been observed with Ge(Li) and Si(Li) detectors from 5 to 300 keV and conversion electrons have been measured from 15 to 300 keV. Low energy (n, γγ) coincidences and half lives of transitions have been measured. The data, combined with three very recent studies of the 8− isomer decay in154Eu has led to the construction of a level scheme with 12 excited levels.
