Study of the isotonic shifts of charge form factor for the light proton-rich nuclei

Structure of23Al from a multi-channel algebraic scattering model based on mirror symmetry

“…Figure 4 shows the MCAS spectrum of 23 Al that results from using the parameter set of table 1, with the addition of the Coulomb potential derived from the charge distribution of [33]. This is compared to the few observed states of 23 Al.…”

“…As the + p 22 Mg central potential depth, V 0 , is much greater than the other components of the nuclear potential, slight adjustments can be used to alter the binding of all calculated compound states without altering the spacing between them. Using the RMF-derived charge distribution from [33], a value of −50.372 MeV for the central well depth for positive parity states, + V 0 , reduces the ground state binding by the 229 keV necessary to obtain a match with data. For the same increase in energy of the first calculated negative parity state, with…”

“…The other states of [4] are not recreated as these are in an energy regime that is higher than where this MCAS calculations is most accurate. 6 shows several low-energy elastic scattering cross sections obtained using the charge distribution of [33] and the same nuclear parameter set as for the n+ 22 investigation. Figure 7 presents cross sections that result from the adjustment of + V 0 and -V 0 detailed previously.…”

“…In the interim, charge-distribution information from other theories may be used in generating Coulomb potentials for calculations of proton-nucleus cluster structure and proton scattering with these nuclei. One such theory, the relativistic mean-field (RMF) model [31], was used recently by Wang and Ren [32,33] to calculate charge distributions for light protonrich nuclei, the properties of which they later compared with standard parameterised functions of charge distribution [34]. In particular, they found an RMF charge distribution for 22 Mg with an rms charge radius, R c shows the Coulomb potential that results from assuming a point-like 22 Mg target, i.e., = V e r 12 Coul 2 .…”
