Energy Levels of Isobaric Nuclei (16N, 16F) within the Modified Surface Delta-Interaction Model

Abstract

The modified surface delta-interaction model is applied to calculate the energy levels of 16N and 16F) nuclei. The good agreement between theoretical and experimental data is attained for excitation energies. This indicates that the shell model describes properly the structure of these nuclei.

Level Structure of 58Cu Within Modified Surface Delta-Interaction

“…V is the matrix element [ 11,12,14] If the 2 particles occupy the same level, the energy relative to the closed shell is: then their energies with respect to the core are given by [11,13,15] 11…”

“…In the mass range A =50 to 102, J. Kostensalo and J. Suhonen [9] calculated the characteristics pairing interaction for even-even) reference nuclei. We used modified surface delta interaction and surface delta interaction to investigate the excitation energies for states two-hole and twoparticle [10,11,12], one particle -one hole [13,14]. In conclusion, investigations accept the new study's purpose, primarily by the use of MSDI, which predicts low-lying levels structure of 58 Cu nuclei.…”

Energy levels of nuclei 40Sc and 40K as a function of semi-classical coupling angle θ1,2 within the modified surface delta-interaction

“…Such a form of interaction is called MSDI. The antisymmetrized matrix element of 1,2 V is given by [11,12,28,29]…”

“…The residual interaction is given by the MSDI defined in Eq. (6), the matrix of the Hamiltonian is [28,29]  …”

“…Recently we studied the energy level of 210 Po within the framework of the SDI [27]. Energy levels of isobaric nuclei 16 N, 16 F within the MSDI were studied [28] by D. N. Hameed and A. K. Hasan. Previous studies motivate the aim of the present work by application of MSDI to calculate the energy levels of isobaric nuclei ( 40 Sc and 40 K) in ph state.…”
