Abstract
| The extremely neutron-deficient isotopes $^{177,179}$Au were studied by means of in-beam γ -ray spectroscopy. Specific tagging techniques, α -decay tagging in $^{177}$Au and isomer tagging in $^{179}$Au, 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 $^{177}$Au. 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. |
