摘要：

An intermediate energy proton scattering experiment has been performed to probe spin excitation in the deformed rare earth nuclei 154Sm, 158Gd and 168Er for energies up to 12 MeV. A concentration of spin M1 strength is observed between 6 and 10MeV with a total strength of about 11 μN2 independent of the nucleus. The strength function shows two distinct structures separated by about 2.5 MeV and each having a width of about 2 MeV. © 1990.
