Description
Nowadays, in nuclear physics, as in many other scientific fields, experiment and theory are strongly linked. The combination of the two studies has led to significant advances in our understanding of the structure and behavior of atomic nuclei, in particular, the energy spectra and various other spectroscopic properties of nuclei throughout the sd shell region. These nuclei are mainly characterized, at low excitation energy, by the coexistence of normal positive parity states, called also 0ħω states, and intruder negative parity states, called also 1ħω states.
We are interested in our work to the study of the 28Al spectroscopic properties within the shell model framework. We performed a shell model calculation using the (0+1)ħω PSDPF interaction [1] and code Nathan [2] to describe the complete energy spectrum of both positive and negative parity states of the 28Al, up to ∼ 6.6 MeV. The different electromagnetic properties were also calculated. The obtained results were compared, then, to available experimental data [3].
This study shows a good agreement theory versus experiment; therefore, many predictions were proposed. A detailed discussion of our work will be presented in this contribution.
Keywords: Nuclear energy spectra, Shell model, Spectroscopic properties, PSDPF interaction, code Nathan.
