We have derived the rates for six of the most important electron capturing nuclei, {54,56,58}Mn and {56,58,60}Co, based on calculations of the Gamow-Teller strength distributions for the ground states and first excited states. These calculations have been performed by shell model diagonalization in the pf shell using a recently modified version of the KB3 interaction. The shell model rates are noticeably smaller than the presently adopted rates as the latter ha","authors_text":"G. Martinez-Pinedo, K.
