Jm. Udias et al., RELATIVISTIC ANALYSIS OF THE PB-208(E,E'P)TL-207 REACTION AT HIGH MOMENTUM, Physical review. C. Nuclear physics, 53(4), 1996, pp. 1488-1491
The recent Pb-208(e,e'p)Tl-207 data from NIKHEF-K at high missing mome
ntum (p(m)>300 MeV/c) are compared to theoretical results obtained wit
h a fully relativistic formalism previously applied to analyze data on
the low missing momentum (p(m)<300 MeV/c) region. The same relativist
ic optical potential and mean-field wave functions are used in the two
p(m) regions. The spectroscopic factors of the various shells are ext
racted from the analysis of the low-p(m) data and then used in the hig
h-p(m) region. In contrast to previous analyses using a nonrelativisti
c mean-field formalism, we do not find a substantial deviation from th
e mean-field predictions other than that of the spectroscopic factors,
which appear to be consistent with both low- and high-p(m) data. We f
ind that the difference between results of relativistic and nonrelativ
istic formalisms is enhanced in the p(m)<0 region that will be interes
ting to explore experimentally.
