Abstract
In a recent article, G. Malle and G. Navarro conjectured that the p-blocks of a finite group all of whose height 0 characters have the same degree are exactly the nilpotent blocks defined by M. Brou´e and L. Puig. In this paper, we check that this conjecture holds for spin-blocks of the covering group 2.An of the alternating group An, thereby solving a case excluded from the study of quasi-simple groups by Malle and Navarro.
