Investigation of low-lying states of 15N via 14N(d, p)15N reactions with vector polarized deuterons

The structure of the natural and unnatural parity states of the15N-15O mirror pair, as well as theT=3/2 analogue states of15C, is discussed in terms of shell model calculations with a modified surface delta two-body interaction. The inert core is recomposed from4He to12C and the configuration space is systematically expanded to allow for an increasing number of particle excitations from the 1p into the 2s-1d shell. The relative importance of the 2s 1/2, 1d 5/2 and 1d 3/2 orbitals are evaluated. Some electromagnetic properties of levels are also calculated.

The effect of expansion of the shell model space on the structure of the mass-15 nuclei

The nuclear properties of the low-lying negative parity states in75As are discussed in terms of the excited-core model. The core and particle parameters were determined by a simultaneous fitting of the available data into a least square iteration program.
