Further Comparisons and Shell-Model Analysis for Nuclei withN=28,20<Z<~28

Comparisons are given between newly available experimental information about electromagnetic transitions in ${}_{}{}^{52}{}_{}{}^{}\mathrm{Cr}$, ${}_{}{}^{53}{}_{}{}^{}\mathrm{Mn}$, and ${}_{}{}^{54}{}_{}{}^{}\mathrm{Fe}$ and the theoretical predictions of a recently presented mixed-configuration shell-model calculation which permits small $2p_{\frac{3}{2}}$ and $1f_{\frac{5}{2}}$ admixtures in the $1f_{\frac{7}{2}}$-shell states. The agreement obtained between theoretical and measured values supports the conclusion that this model gives a good picture of $E2\mathrm{}$ and $M1\mathrm{}$ transition strengths as well as level spacings and proton spectroscopic factors in this region.
