Abstract
The dissipative excitation functions of the 19F+63Cu reaction have been measured in the energy range Elab=100 to 108 MeV in 250 keV energy steps at angles lab=10°,20°,30°,40°,50°. The energy-coherence width of the cross section has been determined by means of the spectral-density method. The results concerning the 19F+63Cu and 28Si+48Ti reactions are compared to evidence the angular momentum effects on the cross-section autocorrelation function. The probability distribution of the cross section is considered in discussing the possible selective excitation of intermediate-system doorway states. © 1989 The American Physical Society.File in questo prodotto:
