Abstrakt:
Detailed fine-structure alpha-decay studies of 188,190Bi were performed using the complete-fusion
reactions of 50,52Cr ions with a 142Nd target at the velocity filter SHIP. The evaporation residues were
separated in-flight and subsequently identified on the basis of recoil-alpha, recoil-alpha-gamma/X-ray and excitation
function measurements. Improved data on the alpha-decay of 188,190Bi were obtained and a number of new
low-lying excited states in the daughters 184,186Tl were observed. An intruder, presumably 10- state was
identified in 184Tl, extending the systematics of such states in the odd-odd Tl nuclei beyond the neutron
mid-shell at N = 104. Some technical aspects of experiment at recoil separators are also discussed.
