Normalization constant of the (α, t) reaction

Summary The DWBA analyses are performed for the ground states and other strong transitions populated in the (α, t) reaction on various targets ranging from A = 16 to 208 with zero-range and with finite-range corrections in the local energy approximation (LEA). The normalization constants without and with the LEA are found to be, respectively, D 2 0 = (18.16±3.49) × 10 MeV fm and D = (8.67±1.60)× 10 MeV 2 fm 3 which are reasonably consistent with some other previous studies. The normalization constants for the (α, t) reaction on the Al target are also deduced for different incident energies E α = 25.0, 25.2, 64.5, 80.0 and 104.0 MeV for studying any possible energy dependence of the normalization constant. No tangible energy dependence was found in the present study and hence the LEA seems to be valid reliably within the energy range studied. The ratio D 2 0 / D bears a value of about 2.0 which is remarkably constant over the target masses and incident energies.
