Abstract：
A method for extracting the empirical proton-neutron interaction energy between the last proton and the last neutron,δV_pn has been discribed and developed.The results for ground states of all even-even nuclei with N not less than 40 and for high spin states of some nuclei have been discussed.δV_pn values at high frequency for given configuration of some odd a nuclei were shown as well.It is found that these empirical δV_pn values include all multipole (mostly the monopole and quadrupole) terms of proton-neutron interaction and sensitively depend on nuclear deformation,configuration and rotational frequency.
