Statistical analysis of the (d,p) and (d,d) reactions on 40Ca

Excitation functions of the 40Ca(d,p)41Ca and 40Ca (d,d)40Ca reactions have been measured at 450, 900, 1350 and 1700 from Esub(d) = 4.50 to 5.43 MeV in 10 keV steps. Angular distributions of these reactions have been taken at Esub(d)= 4.70, 5.00 and 5.30 MeV from 250 to 1700 in 50 steps. Transitions were observed to the excited states for the range 0.0 <= Esub(x) <= 3.74 MeV in 41Ca. Rapid fluctuations in the excitation functions and strong variations of the angular distributions with the incident energy were observed, suggesting that the contribution from compound nucleus processes is very large. Various quantities extracted from the experimental data were compared to the predictions of the statistical theories combined with the DWBA theory for the calculation of the direct reaction amplitudes. The results of the present analysis are consistent with the predictions of the standard statistical theories based on the neglect of the channel-channel correlation. (orig.)
