Scattering of Alpha Particles byCr52,Cr53, andV51

Abstract

The scattering of various-energy alpha particles by ${\mathrm{Cr}}^{52}$ has been studied. The spins and parities of most of the ${\mathrm{Cr}}^{52}$ levels up to 7 MeV were either assigned or confirmed. The reduced transition probabilities $B\left(\mathrm{EI}\right)\mathrm{}\downarrow$ for several levels were determined with the aid of the Austern-Blair model. Similar measurements with 50-MeV alpha particles on ${\mathrm{Cr}}^{53}$ and ${\mathrm{V}}^{51}$ were made and some evidence is considered for the description of ${\mathrm{Cr}}^{53}$ as a ${\mathrm{Cr}}^{52}$ core coupled to an odd neutron.
