Shell-model Interpretation of the Intruder States in <sup>38</sup>Cl <sup> </sup>
ORAL
Abstract
The excited states in 38Cl were populated by the 26Mg(18O, αpnγ)38Cl fusion evaporation reaction at Elab=50 MeV in John. D. Fox laboratory, Florida State University. The experimental observations have been interpreted by shell model calculations using FSU-A interaction, currently being developed by our group [1]. In this interaction, we have chosen the approach of fitting experimental data started from an existing interaction. The single particle energies of the fp shell orbitals along with the monopole terms from the sd-pf cross shell two body matrix elements were adjusted to fit the experimental data compiled from the nuclei ranging from 23Ne to 40K. The interaction well explains 0hbarΩ and 1hbarΩ states in 38Cl. FSU-A also predicts 0p-0h and 1p-1h states of the nearby isotopes which will also be discussed along with future plans to refine this interaction to make it more universal.
