Magnetic Moment and Core Excitation of thed32Hole State inSc47

The magnetic moment of the 760-keV level in ${\mathrm{Sc}}^{47}$ has been measured, using the ${\mathrm{Ca}}^{44}(\alpha , p){\mathrm{Sc}}^{47}$ reaction and the differential time-delay technique, as $\mu =0.35\mathrm{}\pm 0.05$ nm. The half-life for this level was measured as $t_{\frac{1}{2}}=274\mathrm{}\pm 10$ nsec. This magnetic-moment result is consistent with an interpretation for this level of no core-excitation admixtures in the $d_{\frac{3}{2}}$ hole wave function.
