Abstract
A comparison of the pattern of level energies of the ground state bands in even-even Cd and Te nuclei indicates that in Te nuclei for which proton and neutron orbits belong to the same major shell (50 to 82), pronounced neutron-proton interaction occurs. This explains the large h11/2 admixture to the proton configuration of the neutron rich Te isotopes underlying the negative quadrupole moments commented on by Hall and Thomas.
