Description
Low-spin states of 186Au have been studied from the β+/EC decay of 186Hg using the ISOCELE facility. Precise conversion-electron measurements were performed with a semicircular magnetic spectrograph. The 186Au level scheme has been established with spin and parity assignments deduced from transition multipolarities and log ft values. It shows two separate groups of levels which could be interpreted as due to shape coexistence: prolate deformation for the first low-lying states, and oblate deformation for the 251.5 keV (2-) and 363.6 keV (1+) states.
