Spectroscopic factors of six low-lying neutron hole states in {sup 207}Pb 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 {sup 208}Bi into the neutron hole states in {sup 207}Pb. The spectroscopic factor for the 2f{sub 7/2} hole state shows a strong quenching (about 50{percent} 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. {copyright} {ital 1997} {ital The American Physical Society}
