“…These fundamental forms of the potential have been successful in describing α-scattering by Ca [51], Ni [52], Mg and Si [60]. The calculated α-α potentials, obtained from the EDF theory, are parametrized using the real part of both the functional forms in (9) and (10), and are noted in Table 1 as the V edf (GG) and V edf (WG) sets.…”

“…The α scattering on some light and medium-heavy nuclei exhibit strong enhancement of cross section at backward angles [i.e., the so-called anomalous large angle scattering (ALAS)]. This phenomenon brought considerable interest and was explained by various approaches (e.g., modified WoodsSaxon potential, L-dependent potential, folding potential, α exchange, Regge poles, and so on [1][2][3][4][5][6][7][8][9][10][11][12]). …”

“…Interestingly the EDF calculations, with the Pauli-exchange effect incorporated in the mean field, leads to a shallow non-monotonic (NM) real part of the potential. EDF predictions have been used as guides in parametrizing phenomenological potentials for α- 28 Si over a limited range of incident energies [6] and then over a larger range for the α elastic scattering data on [28][29][30] Si, 24 Mg, 27 Al, 40,44,48 Ca and Ni-isotopes [7][8][9]. Recently it has been observed that the NM potential generated by the EDF procedure can fit α + α scattering data at low incident energies without any adjustment [10] and scattering from Ni-isotopes with some modifications [9].…”

“…However, as discussed in refs. [6][7][8][9][10], the BE of an α-particle from the best available density distribution was low, being BE = 20 MeV compared to its observed value of 28 MeV. This might explain, as hinted in [10], why the raw EDF-derived α-potential needs a modification of parameters to satisfactorily account for the α-nucleus elastic scattering data.…”
