Comparison of magnetic dipole excitations in thef7/2shell region with the new collective excitations inGd156

It is noted that in a single j shell ($f_{7/2}$) calculation in the titanium isotopes one obtains M1 rates of about one single particle unit in strength to states at about 4 MeV excitation. This is systematically consistent with the recently discovered collective excitations in ${}_{}{}^{156}{}_{}{}^{}\mathrm{Gd}$, and neighboring nuclei. In the single j shell case, though, the spin and orbital contributions to the M1 matrix element are nearly the same.
