First Time

Excited states in the Tz = -1 nucleus 44 V have been observed for the first time. The states have been identified through recoil-γ-γ coincidences and comparison with analogue states in the mirror nucleus 44 Sc . Mirror energy differences have been extracted and compared to state-of-the-art fp shell-model calculations which include charge symmetry breaking forces.

The Future

The purpose of this work is to describe, in light of shell model calculations using the PSDPF interaction, the particular states with J = 0 in sd shell nuclei. These states are difficult to observe. It is well known that the ground state in even–even nuclei has Jπ = 0+ and therefore we are interested in describing their first excited [Formula: see text] states. We have also studied the first and second excited 0− states in all sd nuclei. The experimental and theoretical excitation energies of these states were confronted. This study allowed us to make predictions of the existence of [Formula: see text] and (or) [Formula: see text] states in nuclei, which do not possess these states, or to have an idea of their excitation energies for possible experiments in the future.

Tensor Correlation

We investigate the roles of the tensor correlation on the structures of 4 He and 5 He . For 4 He , we take the high angular momentum states within the 2p2h excitations of the shell model type method to describe the tensor correlation explicitly. We found that the solutions show a good convergence and the obtained wave function has the large tensor correlation. We also found that three 2p2h configurations are largely coupled with (0s)4 one to describe the tensor correlation, which is understood from the selectivity of the tensor operator. This tensor correlation is also important to describe the scattering phenomena of the 4 He +n system including the higher partial waves consistently.

Nuclear Shell

An examination is made of the possible errors that may arise in nuclear shell-model calculations by failing to separate out centre-of-mass motions from the internal motions of the system; a central oscillator potential is used to make possible a simple analysis. The most important effect is the appearance of spurious states that do not refer to the internal motion at all; these must be considered whenever the state is described by two or more unclosed shells (in the sense of L-S coupling), as, for example, in the excited states of 16 O.
