Abstract

The high-spin normally deformed and superdeformed states of 194Hg have been populated in an exit channel of the 16O+186W reaction at 110 MeV bombarding energy. The Doppler shift analysis of the energies of the γ transitions de-exciting both normally deformed and superdeformed states in 194Hg indicates a lower recoil velocity of the 194Hg nucleus compared to that of the 196Pb nucleus obtained from the 6n exit channel of the complete-fusion compound nucleus. This suggests that incomplete fusion plays the main role in the population of normally deformed and superdeformed states of 194Hg in this reaction.
