K-capture cosmic ray secondaries and reacceleration

We have investigated the effect of reacceleration on interstellar flux of K-capture secondaries 49V and 51Cr. Several isotopic ratios for these two isotopes are calculated using the galactic diffusion model with and without distributed reacceleration. It is found that the statistical accuracy of the...

Description
Summary:We have investigated the effect of reacceleration on interstellar flux of K-capture secondaries 49V and 51Cr. Several isotopic ratios for these two isotopes are calculated using the galactic diffusion model with and without distributed reacceleration. It is found that the statistical accuracy of the ACE experiment on itself is high enough to see a signature of reacceleration. However, the uncertainties in nuclear production cross sections are probably too large to conclude that reacceleration process took place.
