“…It may seem surprising that the effective C4 isoscalar charge (2.0e) is BROWN & WTLDENTHAL larger than the effective C2 isoscalar charge (1.6-1.8e). However, this larger value is consistent with a calculation for the coupling of the sd-shell valence orbits to the C4 giant resonance (126). It would be interesting to continue such comparisons for the higher-multipole (L > 4) longitudinal form factors in heavier nuclei.…”

“…However, for the 4 + 1 (K π = 0 + ) state, such reaction calculations with phenomenological collective models have failed to describe the angular distribution of the (p, p ) cross sections. Further, microscopic approaches have been applied to calculate the inelastic scattering of protons [14,27] and the inelastic charge form factors [9,36]; however, no microscopic calculation has succeeded in reproducing the property of the 0 + 1 → 4 + 1 transition. In inelastic scattering, the 4 + 1 (4.12 MeV) state is weakly produced compared to the 2 + 2 (4.24 MeV) state at close energy.…”

Background The triaxial and hexadecapole deformations of the K π = 0 + and K π = 2 + bands of 24 Mg have been investigated by the inelastic scatterings of various probes, including electrons, protons, and alpha(α) particles, for a prolonged time. However, it has been challenging to explain the unique properties of the scatterings observed for the 4 + 1 state through reaction calculations.Purpose To investigate the structure and transition properties of the K π = 0 + and K π = 2 + bands of 24 Mg employing the microscopic structure and reaction calculations via inelastic proton and α-scattering. Particularly, the E4 transitions to the 4 + 1 and 4 + 2 states were reexamined. Method The structure of 24 Mg was calculated employing the variation after the parity and total-angular momentum projections in the framework of the antisymmetrized molecular dynamics (AMD). The inelastic proton and α reactions were calculated by the microscopic coupled-channel (MCC) approach by folding the Melbourne g-matrix N N interaction with the AMD densities of 24 Mg.Results Reasonable results were obtained on the properties of the structure, including the energy spectra and E2 and E4 transitions of the K π = 0 + and K π = 2 + bands owing to the enhanced collectivity of triaxial deformation. The MCC+AMD calculation successfully reproduced the angular distributions of the 4 + 1 and 4 + 2 cross sections of proton scattering at incident energies of Ep = 40-100 MeV and α-scattering at Eα = 100-400 MeV.Conclusions This is the first microscopic calculation that described the unique properties of the 0 + 1 → 4 + 1 transition. In the inelastic scattering to the 4 + 1 state, the dominant two-step process of the 0 + 1 → 2 + 1 → 4 + 1 transitions and the deconstructive interference is the weak one-step process were essential.
