Abstract
Excitation functions of proton elastic scattering on the even-even nuclei Cr54 and Fe56 have been measured at incident proton energies from 9.3 to 10.11 MeV in 5 keV steps and from 9.27 to 9.57 MeV in 2 keV steps respectively and from 11.5 to 11.9 MeV in 5 keV steps for Fe (p,p0) only. Seven silicon surface barrier detectors were used to get angular distributions from 63° to 173°. The observed cross-section fluctuations are interpreted in terms of ERICSON'S statistical theory. From the strength of the fluctuations differential compound elastic cross-sections are deduced. The results are compared with HAUSER-FESHBACH calculations and are generally discussed with respect to the optical model.Keywords
