Depletion of the [Formula Presented] neutron hole state in [Formula Presented]

Spectroscopic factors of six low-lying neutron hole states in ${}^{207}\\mathrm{Pb}$ 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 ${}^{208}\\mathrm{Bi}$ into the neutron hole states in ${}^{207}\\mathrm{Pb}.$ The spectroscopic factor for the ${2f}_{7/2}$ 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 $2p\\ensuremath{-}1f$ and $3p\\ensuremath{-}2f$ shell regions is discussed.
