We reevaluate some of the data presented recently by Hinnefeld er al. [Phys
. Rev. C 58, 2563 (1998)] and use, in particular, a more accurate value for
the ratio Gamma(gamma)/(p), of the partial widths of the 2750 keV level in
K-37. Our analysis essentially confirms the conclusion drawn by these auth
ors concerning the rapid depletion of Ar-36 at explosive hydrogen-burning c
onditions. [S0556-2813(99)03907-2].
