Direct empirical correlation between proton-neutron interaction strengths and the growth of collectivity in nuclei

Phys Rev Lett. 2006 Apr 7;96(13):132501. doi: 10.1103/PhysRevLett.96.132501. Epub 2006 Apr 7.


A direct correlation between experimental values of proton-neutron interaction strengths and experimental measures of the growth of collectivity in nuclei is found. In particular, differences in the p-n interaction strengths and differences in growth rates of collectivity in particle-particle (or hole-hole) and particle-hole regions are found to correspond.
