Proton Angular Distributions fromCr52,53(d, p)Reactions

Abstract

Targets enriched in ${\mathrm{Cr}}^{52}$ and ${\mathrm{Cr}}^{53}$ were bombarded with 10-Mev deuterons. Angular distributions were measured and $Q$ values determined for four proton groups from ${\mathrm{Cr}}^{52}(d, p){\mathrm{Cr}}^{53}$ and for six groups from ${\mathrm{Cr}}^{53}(d, p){\mathrm{Cr}}^{54}$. For the former reaction the $Q$ values were 5.74, 5.17, 4.77, and 3.43 Mev. For the latter the $Q$ values were 7.55, 6.69, 6.24, 4.88, 4.36, and 3.76 Mev. All angular distributions were of type $l_n=1\mathrm{}$ except for $Q=4.77\mathrm{}$ Mev in ${\mathrm{Cr}}^{52}(d, p)$, for which $l_n=3\mathrm{}$. The latter group is interpreted as possibly a single-particle $f_{\frac{5}{2}}$ state, and these data may therefore reveal the relative position of single-particle $f_{\frac{5}{2}}$ and $p_{\frac{3}{2}}$ levels.
