| 英文摘要 | The thermonuclear rate of the ~(50)Fe(p, γ)~(51)Co reaction in the Type I X-ray bursts (XRBs) temperature range has been reevaluated based on a recent precise mass measurement at CSRe Lanzhou, where the proton separation energy S_P=142±77 keV has been determined firstly for the ~(51)Co nucleus. Comparing to the previous theoretical predictions, the experimental S_P value has much smaller uncertainty. Based on the nuclear shell model and mirror nuclear structure information, we have calculated two sets of thermonuclear rates for the ~(50)Fe(p, 7)~(51)Co reaction by utilizing the experimental S_P value. It shows that the statistical-model calculations are not ideally applicable for this reaction primarily because of the low density of low-lying excited states in ~(51)Co. In this work, we recommend that a set of new reaction rates based on the mirror structure of ~(51)Cr should be incorporated in future astrophysical network calculations. |
