“…, Refs. [2,3] and other references quoted therein). Due to these properties the semimicroscopic approach is also of interest for calculating application oriented data.…”

Validation of an optical potential for incident and emitted low-energy $$\alpha $$-particles in the $$A\sim 60$$ mass range

“…The due consideration of DI role within the α-emission in both neutron-and proton-induced reactions is obviously leading to an increase beyond the PE+HF predictions. Moreover, since the beginning of '90s it is concluded that the pickup instead of knockout has the main DI contribution to the low-lying levels in ( p, α) and (n, α) reactions ( [2,80,100] and Refs. therein).…”

“…The prior form distortedwave transition amplitudes, and the finite-range interaction have been considered. The p-3 H as well as n- 3 He effective interaction in the α particle are assumed to have a Gaussian shape [100,103,104]:…”

“…where r 0 = 2 fm, and V 0 is determined by fit of the binding energies of 3 H and 3 He, respectively. The three-nucleon transferred cluster bound states were generated in a Woods-Saxon real potential [100,[102][103][104] with the depth adjusted to fit the separation energies in the target nuclei. The number of N nodes in the radial three-nucleon cluster wave function was determined by the harmonicoscillator energy conservation rule [101,102]:…”

Cross sections of theNd143(n,α)Ce140

“…Because Q values for the 143 Nd(n,α) 140 Ce and 147 Sm(n,α) 144 Nd reactions are relatively large (9.722 and 10.13 MeV, respectively), cross sections are measurable even at low energies; hence, measurements and analysis have been made at thermal and resonance energies, as well as for 14 MeV neutrons [1][2][3][4][5][6][7][8][9][10][11][12][13].…”
