The collective yrast band and the high spin states of the nucleus {sup 50}Cr are studied using the spherical shell model and the cranked Hartree-Fock-Bogoliubov method. The two descriptions lead to nearly the same values for the relevant observables. A first backbending is predicted at {ital I}=10{h_bar} corresponding to a collective to noncollective transition. At {ital J}=16{h_bar} a second backbending occurs, associated to a configuration change that can also be interpreted as a spherical to triaxial transition. {copyright} {ital 1996 The American Physical Society.}
