Abstract

The 208Pb(t, p)210Pb reaction has been performed at a bombarding energy of 20 MeV. Angular distributions using solid-state counters and a magnetic spectrograph were obtained for levels up to 5 MeV of excitation. The different transitions are interpreted in terms of multipole pair addition modes, and support for the existence of multipole pairing fields is obtained from the analysis. The data are also compared with calculations using realistic force wave functions. No new correlations from the latter calculations not already present in the multipole pairing description were found. Special attention is paid to the transition to the 3 state at 1.869 MeV which has a large component of the two-phonon state ¦3 (208Pb) ⊗ g.s. (210Pb)〉. It is shown that both ground state correlations and indirect transfer processes have to be invoked to explain the data. The two-step processes are treated in the coupled-channel Born approximation.
