We present the ratio of experimental 0° (p, n) cross sections with the measured B(M1) values for transitions in several nuclei. Taking the strong spin-flip transition in 12C for normalization, we find overall good agreement with shell-model predictions for 24Mg, 28Si, and 48Ca. The values of the ratios vary considerably and are very sensitive to the relative amounts of spin and current contributions to each transition. Experimental ratios are also presented for 16O and 26Mg.
