Coincident cross sections were measured for the reaction Au-197(p,p'p'
') at an incident energy of 200 MeV. The protons emitted from the cont
inuum were detected at primary laboratory angles of -40-degrees, -50-d
egrees, and -60-degrees, for secondary angles ranging between 20-degre
es and 150-degrees. The theoretical model which was used to interpret
the coincident spectra describes the reaction mechanism in terms of a
quasifree nucleon-nucleon interaction between the projectile and a bou
nd target nucleon, folded with a probability for emission of the quasi
free knocked-on nucleon after inelastic rescattering off the residual
target nucleus. The validity of the distorted-wave impulse approximati
on which describes the initial quasifree interaction was confirmed by
measuring the quasifree knockout of valence-orbital protons from Au-19
7. The measured coincident continuum cross sections were then compared
with model calculations for primary proton energy cuts around 90, 70,
and 40 MeV. The reasonable agreement found between the calculated and
measured cross sections indicates that the signature of quasifree sca
ttering persists in the continuum emission from a nucleus as heavy as
Au-197, and is not obscured by multiple scattering effects.
