THE PROTON STRENGTH DISTRIBUTION OF THE DISCRETE HOLE STATES OF TL-207

The proton strength distributions of the discrete hole states of Tl-20 7 have been deduced within the framework of the Hole-Core vibrational scheme. The spectroscopic factors of the low-lying states have been co mpared with the recent experimental works performed with the help of e nergetic polarised deuteron beam. The loss of shell-model identities o f these discrete proton states are explained due to strong mixing of t he proton hole orbitals with the collective vibrational states of Pb-2 08 core nucleus including the ones arising from the giant resonances.
