Microscopic description of neutron and proton transition moments in spherical nuclei

Neutron and proton transition matrix elements for low-lying quadrupole transitions are calculated microscopically in the framework of the quasiparticle phonon nucleaar model in some spherical nuclei. For isoscalar states Mn and Mp are of the same value and sign, and for the isovector states they are predicted to be of the same value and opposite sign. The isoscalar and isovector states are differently excited in inelastic scattering of protons and deuterons. 13 refs.; 2 tabs
