Abstract
The differential cross sections of the (p, p')
inelastic reaction on nuclei 12C, 28Si,
40Ca, and 56Fe at the initial proton energy of 1 GeV were measured
over a wide range of the scattered proton momenta at a laboratory angle of
Θ=21°. Scattered protons were detected by means of the
magnetic spectrometer equipped with a polarimeter based on multiwire
proportional
chambers. Momentum intervals were observed in which the ratios of the
scattering
cross sections off the nuclei do not depend on the scattered proton momentum
(i.e., scaling).
