Levels in 153Eu and 155Eu Populated by the Beta Decay and (3He,d) Reactions

Abstract

Thirty-one excited levels in 153Eu and thirty-four in 155Eu have been located by means of the (3He,d) and beta decay reactions. The energies, intensities, and decay scheme classifications of forty-four gamma rays in 153Eu and fifty-two in 155Eu have been measured by means of singles and coincidence experiments using NaI and Ge(Li) detectors. Angular distribution studies of the reaction deuterons have been made a number of levels have neen assigned unique l values. An interpretation of the level schemes in terms of the Nilsson model have been attempted.
