摘要：

High-momentum components of proton momentum distributions in Pb208 have been studied from 300 to 500 MeV/c with the (e,e′p) reaction. Cross sections were measured with 180 keV excitation-energy resolution for transitions to the low-lying 1/2+, 32+, 112-, 52+, and 72+ states in Tl207. 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. © 1994 The American Physical Society.
