Beschreibungen/Notizen

• High-momentum components of proton momentum distributions in [sup 208]Pb have been studied from 300 to 500 MeV/[ital c] with the ([ital e], [ital e][prime] [ital p]) reaction. Cross sections were measured with 180 keV excitation-energy resolution for transitions to the low-lying 1/2[sup +],3/2[sup +],11/2[sup [minus]],5/2[sup +], and 7/2[sup +] states in [sup 207]Tl. The data are compared to distorted-wave impulse-approximation calculations with mean-field wave functions and with wave functions that include nucleon-nucleon correlations. The data are substantially larger than mean-field predictions. The observed excess strength at low excitation energy appears to be mainly due to long-range correlations and not to short-range and tensor correlations.
