Abstract: | The high resolution (3He,α) reaction on206Pb shows the distribution of the 2f 7/2, 1h 9/2 and 1i 1 3/2 neutron states of205Pb within the 6 MeV excitation energy of205Pb. The spectrum of these three-hole states is obtained within the hole-core vibrational coupling scheme. The shell model energies of the neutron hole states arising from the core-polarization effect are compared with the Bansal-French energy weighted sum rule. The possible implication of the present neutron hole energies has been discussed in the light of the deduced shell model wave functions of the collective states of206Pb. |
