Abstract
Highly excited states in the nucleus Hg-193 have been investigated by in-beam gamma-ray spectroscopic techniques using the EUROGAM array. Th e reaction Nd-150 (Ca-48,5n) at a beam energy of 213 MeV was used to p opulate states of Hg-193. The level scheme has been considerably exten ded (up to 10.7 MeV) and enriched from earlier studies. Two new struct ures of competing dipole and quadrupole transitions were observed. Exp erimental B(M1)/B(E2) ratios were determined for the two structures an d compared with theoretical estimates. They were also compared with si milar structures in the neighbouring Hg and Pb nuclei.
