Average entry points for superdeformed (SD) and normal states have been measured in {sup 191, 192}Hg and in {sup 152}Dy. Compared with normal states, the superdeformed states have entry spins {approximately} 10 h higher and internal excitation energies (U = E --- E{sub yrast}) at least 2 MeV lower for the Hg cases and about 8 MeV lower for {sup 152}Dy. By comparison with calculated {ell}- distributions of evaporation residues (ER), using CASCADE to compute the fission competition, we find that the initial population of the SD band in {sup 192}Hg originates from the tail of the ER spin distribution. 12 refs., 5 figs.
