Shape coexistence in 180Hg studied through the β decay of 180Tl

The β+/EC decay of 180Tl and excited states in the daughter nucleus 180Hg have been investigated at the CERN On-Line Isotope Mass Separator (ISOLDE) facility. Many new low-lying energy levels were observed in 180Hg, of which the most significant are the second 0+ at 419.6 keV and the second 2+ at 601.3 keV. The former is the bandhead of an excited band in 180Hg assumed originally to be of prolate nature. From the β feeding to the different states in 180Hg, the ground-state spin of 180Tl was deduced to be (4−,5−).
