Spectroscopic factors of six low-lying neutron hole states in 207Pb were measured with a (p,d) reaction at 65 MeV. The results are compared with previous (p,d) reaction data as well as recent escape width ones of isobaric analog states in 208Bi into the neutron hole states in 207Pb. The spectroscopic factor for the 2f7/2 hole state shows a strong quenching (about 50% of the sum-rule limit), which suggests the existence of considerable strengths in higher excitation energy region. The appearance of the fragmentation or quenching in neutron hole strength distribution observed in the 2p−1f and 3p−2f shell regions is discussed.
