Abstract: (APS)
The lack of knowledge of the 45V(p,γ) reaction rate has been shown to contribute a large uncertainty to the production of 44Ti in core-collapse supernovae. By considering likely contributions from resonances associated with 46Cr states that are the isobaric analog of states in 46Ti, we have determined that the currently accepted value of the 45V(p,γ) reaction rate is unlikely to be inaccurate by more than an order of magnitude. These conclusions are confirmed by the shell model calculations with the FPD6 effective interaction.- 26.50.+x
