“…The unperturbed energies for the single particle-hole states for both positive and negative parity states used in this work are adopted from our previous theoretical work (see Table 1 and 2 from Ref. [6]). Higher configurations are included in the calculations when the ground state is considered as a mixture of the |(1s 1/2 ) 4 (1p 3/2 ) 8 and |(2s 1/2 ) 4 (2p 3/2 ) 8 configurations, such that the ground state wavefunction becomes…”

“…Coulomb form factors of C2 transitions in several selected p-shell nuclei are discussed by Radhi et al [5] taking into account corepolarization effects. The configuration of the mixing shell model has been recently used [6] to study the isovector states of 12 C in the framework of particle-hole theory. The calculations are quite successful and describe very well the experimental form factors for all momentum transfer regions.…”

Electron scattering form factors from 12 C have been studied in the framework of the particle-hole shell model. Higher configurations are taken into account by allowing particle-hole excitations from the 1s and 1p shells core orbits up to the 1f -2p shell. The inclusion of the higher configurations modifies the form factors markedly and describes the experimental data very well in all momentum transfer regions.

“…For example, shell model calculation of A = 41 -43 nuclei [9]. The modified schematic shell model for ph configuration within SDI [1,10] and MSDI has been applied to various nuclear structure states [11,14] Lawson and Talmi [15,16] studied the spectra 38 Cl, 40 K and 40 Ca by employing the Pandya transformation between particle-particle (pp) spectra such as 38 Cl and ph spectra as such as 40 K.

In this work, nuclear shell model was applied using modified surface delta-interaction to calculate, in particle-hole state, the energy levels of isobar nuclei 40 Sc and 40 K. Particles are in the model space (1f 7/2 ) while the holes are found in the model space (1d 3/2 , 1s 1/2 , 1d 5/2 ). The total angular momentum and parity are identified for possible particles and holes in nuclei above. Thus, we have used a theoretical study to find relationship between energy levels and the semiclassical coupling angle θ 1 , 2 at different orbitals within particle-hole configuration. We notice the energy levels seem to follow two universal functions which depend on the semi-classical coupling angles θ 1,2 . We found the theoretical data agree to the experimental data.

Inelastic longitudinal electron scattering form factors for secondexcited state C42 in 42Ti nucleus have been calculated using shellmodel theory. Fp shell model space with configuration (1f7/2 2p3/21f5/2 2p1/2) has been adopted in order to distribute the valenceparticles (protons and neutrons) outside an inert core 40Ca. Modernmodel space effective interactions like FPD6 and GXPF1 have beenused to generate model space vectors and harmonic oscillator wavefunction as a single particle wave function. Discarder space (coreorbits + higher orbits) has been included in (core polarization effect)as a first order correction in microscopic theory to measure theinterested multipole form factors via the model space.Gogny and Michigan sum of three-range Yukawapotential (M3Y-p2) have been utilized as a residual interaction tocouple the (particle-hole) pair across the model space active particlesand the excitation energy of the pair is (2ħω) and four options for theused effective and residual interactions were determined for thetransitions from (+0) to (+01,2,3), (+21,2,3) and (+41,2,3).
