Abstract:
The extremely neutron-deficient isotopes Au-177,Au-179 were studied by means of in-beam gamma-ray spectroscopy. Specific tagging techniques, alpha-decay tagging in Au-177 and isomer tagging in Au-179, were used for these studies. Feeding of positive-parity, nearly spherical states, which are associated with 2d(3/2) and 3s(1/2) proton-hole configurations, from the 1i(13/2) proton-intruder configuration was observed in Au-177. Such a decay path has no precedent in odd-Au isotopes and it is explained by the effect of mixing of wave functions of the initial state. (C) 2020 Published by Elsevier B.V.
