Abstract
The heaviest = 127 even-odd isotone was produced in a fusion evaporation reaction employing ions bombarding target. Fusion evaporation residues were separated in flight by the gas-filled recoil separator Spectrometer for Heavy Atoms and Nuclear Structure and subsequently identified using a recoil- correlation method. The -decay properties of were measured with improved precision, and two new -decay lines were observed and assigned as the decays from the ground state of to the () and () states of , respectively. The systematics for the decay of the = 127 even-odd isotones as well as the low-lying nuclear structure of their = 125 daughter nuclei are discussed.
