Abstract

A broad resonance has been observed by inelastic scattering of 200 MeV protons from 51V, 58,60,62Ni, 68Zn, 90,92,94,96Zr, 92,94,96,98,100Mo, 120,124Sn and 140Ce. The resonance occurs between 8 and 9 MeV in most of the nuclei and has a width of around 2 MeV. In all cases, the angular distribution is very sharply forward peaked and is consistent with an orbital angular momentum transfer of zero. The excitation energy, angular distribution and strength of the resonance suggest that it is the giant M1 resonance. In the nickel isotopes, and in 51V, both the To and To+1 components of the resonance are observed.
