A consistent analysis of (e,e'p) and (d,3He) experiments
The apparent discrepancy between spectroscopic factors obtained in (e,e'p)
and (d,3He) experiments is investigated. This is performed first for
48Ca(e,e'p) and 48Ca(d,3He) experiments and then for other nuclei. It is shown
that the discrepancy disappears if the (d,3He) experiments are re-analyzed with
a non-local finite range DWBA analysis with a bound-state wave function that is
obtained from (e,e'p) experiments.Comment: 23 pages, 7 figure
The He Cross Section at Large Missing Energy
The reaction on nuclei was studied in kinematics
designed to emphasize effects of nuclear short-range correlations. The measured
cross sections display a peak in the kinematical regions where two-nucleon
processes are expected to dominate. Theoretical models incorporating
short-range correlation effects agree reasonably with the data.Comment: 4 pages LaTeX, using espcrc1.sty and wrapfig.sty (included), two

Spectroscopic Factors in Ca and Pb from : Fully Relativistic Analysis
We present results for spectroscopic factors of the outermost shells in
Ca and Pb, which have been derived from the comparison between
the available quasielastic () data from NIKHEF-K and the corresponding
calculated cross-sections obtained within a fully relativistic formalism. We
include exactly the effect of Coulomb distortion on the electron wave functions
and discuss its role in the extraction of the spectroscopic factors from
experiment. Without any adjustable parameter, we find spectroscopic factors of
about 70\%, consistent with theoretical predictions. We compare our results
with previous relativistic and nonrelativistic analyses of () data. In
addition to Coulomb distortion effects we discuss different choices of the
nucleon current operator and also analyze the effects due to the relativistic
treatment of the outgoing-distorted and bound nucleon wave functions.Comment: 9 pages RevTeX, 5 figures can be obtained from the author
