“…Sets of opticalmodel parameters have been found for deuteron elastic scattering by 16 0 for incident deuteron energies between 11.8 and 52 MeV. [31][32][33][34][35][36][37] Many studies have been done with lower energy deuterons, but the applicability of the optical model is questionable in these cases. The parameters used here are based on the 11.8-MeV parameters of Hodgson, 34 the 34.4-MeV parameters of Newman et al, z * and the 52-MeV parameters of Duelli et al z1 Each of these studies used a derivative surface absorption and included spin-orbit effects.…”

Consistent account of deuteron-induced reactions on natCr up to 60 MeV

“…On the whole, the comparison of the present results with TENDL evaluation points out the importance of the new measured cross sections around the maximum of the nat Cr(d, xn) 54 Mn activation as well as the role of breakup and stripping mechanisms to obtain the suitable description of these data. The good agreement of experimental and calculated excitation function shown in Fig.…”

“…14. Additional comments concern several reaction types and residual nuclei as follows. First, one should note the major role of the stripping contribution to the 53 Cr(d, n) 54 Mn excitation function shown in Fig. 9.…”

“…Methods: The activation cross sections of 51,52,54 Mn, 51 Cr, and 48 V nuclei for deuterons incident on natural Cr at energies up to 20 MeV, were measured by the stacked-foil technique and high resolution gamma spectrometry using U-120M cyclotron of the Center of Accelerators and Nuclear Analytical Methods (CANAM) of the Nuclear Physics Institute of the Czech Academy of Sciences (NPI CAS). They as well as formerly available data for deuteron interactions with Cr isotopes up to 60 MeV are the object of an extended analysis of all processes from elastic scattering until the evaporation from fully equilibrated compound system, but with a particular attention given to the BU and DR mechanisms.…”
