“…Still, the RPA root is shifted down in energy by about 1.5 MeV relative to the single ph excitations. These assignments are in reasonable accordance with experimental information from γ decay [45], particle transfer [46], (e,e ) inelastic scattering [47], (α,α ) scattering [48], and (π ,π ) scattering [49].…”

We present a calculation of the properties of vibrational states in deformed, axially-symmetric even-even nuclei, within the framework of a fully self-consistent quasiparticle random phase approximation (QRPA). The same Skyrme energy density and density-dependent pairing functionals are used to calculate the mean field and the residual interaction in the particle-hole and particle-particle channels. We have tested our software in the case of spherical nuclei against fully self-consistent calculations published in the literature, finding excellent agreement. We investigate the consequences of neglecting the spin-orbit and Coulomb residual interactions in QRPA. Furthermore we discuss the improvement obtained in the QRPA result associated with the removal of spurious modes. Isoscalar and isovector responses in the deformed 24-26 Mg, 34 Mg isotopes are presented and compared to experimental findings.

“…The form factors predicted for the 3 − 3 state are remarkably small and their shape is inconsistent with neither the 3 − 1 nor 3 − 2 states meaning that this state has a quite differ- ent character from the lowest two 3 − states. The form factors observed for the 4 + 1 state are much smaller than those for the 4 + 2 state [9]. The present AMD calculation yields small form factors for the 4 + 1 state, which are comparable to the experimental data; however, the shape of the form factors is inconsistent with that is observed.…”

“…For the 4 + 1 (K π = 0 + ) state, a remarkably weak λ = 4 transition was observed in the (e, e ) experiment [9]. The 0 + 1 → 4 + 1 transition strength is more than one order smaller than that for the 0 + 1 → 4 + 2 transition meaning that the λ = 4 strength from the ground state is dominantly concentrated not in the 4 + 1 (K π = 0 + ) state but rather in the 4 + 2 (K π = 2 + ) state.…”

“…The band structure of 24 Mg has been studied via electromagnetic transitions [1][2][3], and intensively investigated through inelastic scattering of various probes, including electrons [4][5][6][7][8][9][10], pions [11], nucleons [12][13][14][15][16][17][18][19][20][21][22][23], 3 He [24,25], and α [25][26][27][28][29]. For inelastic hadron scattering off 24 Mg, detailed reaction analyses have been performed using the distorted-wave Born approximation (DWBA) and coupled-channel (CC) calculations.…”

Shell model calculations based on large basis has been conducted to study the nuclear structure of $^{20}Ne$, $^{22}Ne$ and $^{24}Mg$ nuclei. The energy levels, inelastic electron scattering form factors and transition probabilities are discussed by considering the contribution of configurations with high-energy beyond the model space of sd-shell model space which is denoted as the core polarization (CP) effects.~The Core polarization is considered by taking the excitations of nucleus from the $1s$ and $1p$ core orbits and also from the valence $2s$ $1d$ shell orbit in to higher shells with $4\hbar\omega$. The effective interactions $USDA$ and $USDB$ are employed with $sd$ shell model space to perform the calculation and the core polarization are calculated with $MSDI$ as residual interaction.~The calculated energy level schemes, form factors and transition probabilities were compared with the corresponding experimental data. The effect of core polarization is found very important for the calculation of $B(C2)$, $B(C4)$ and form factors, and gives excellent results in comparison with the experimental data without including any adjustable parameters.
