TITLE=/Preequilibrium (p,p') spectra for nuclei around neutron number
50/;
PURPOSE=/To see how the shell and odd-even effects will appear in the
continuum proton spectra, and to interpret the experimental
results in terms of realistic partial state density within the
framework of the preequilibrium model/;

/* Experimental Method:
- Beam current integrated (Beam intensity was determined with a
current integrator connected to a Faraday cup and was also
monitored by a detector located at a fixed backward angle to the
beam.)
- Particle identification by 'E/Delta E' measurement (Signals of
protons were separated from those of other charged particles with
a particle identification circuit.)

/* Analysis:
- Integration of angular distribution (Experimental angular
distribution for each 0.2 MeV energy bin were fitted with a
series of Legendre polynomials up to l=4, and then the
polynomials were integrated.)

/* '471' Uncertainties associated with the normalization was
estimated to be within 10% for each target. However, the
relative uncertainties of the cross sections for different
targets is believed to be less than 4%. */
NORM=/ Absolute cross sections were determined by normalizing the
experimental elastic cross sections to the optical model
predictions at forward angles. The normalization factors for
two sets of global optical model parameters were compared in
order to estimate the uncertainties involved in this method.
Optical model parameter [F.D. Becchetti, Jr. and G.W.
Greenlees, Phys. Rev. 182(1969)1190] were adopted. /;
