The entry distribution in angular momentum and excitation energy for the formation of {sup 254}No has been measured after the {sup 208}Pb({sup 48}Ca,2n) reaction at 215 and 219 MeV. This nucleus is populated up to spin 22{Dirac_h} and excitation energy {>=}6 MeV above the yrast line, with the half-maximum points of the energy distributions at -5 MeV for spins between 12{Dirac_h} and 22{Dirac_h}. This suggests that the fission barrier is {>=}5 MeV and that the shell-correction energy persists to high spin.
