Abstract
The collective yrast band and the high spin states of the nucleus 50Cr are studied using the spherical shell model and the HFB method. The two descriptions lead to nearly the same values for the relevant observables. A first backbending is predicted at I=10 corresponding to a collective to non-collective transition. At I=16 a second backbending occurs, associated to a configuration change that can also be interpreted as an spherical to triaxial transition.
