Very converted transitions and particle-core coupling in neutron-deficient odd-mass au isotopes

Abstract

Levels in185, 187Au have been studied by radioactive decay of isotopically separated185, 187Hg. A number of low-energy very-converted transitions are observed in the decay. It is shown that the enhanced conversion in these cases comes from an E0 component rather than from an anomaly in theM1 conversion process. A systematic pattern of bands interconnected with these very converted transitions is presented as evidence for a new type of particle-core coupling in185, 187Au.
