Stability Of The Solution

We have performed angular momentum projection with double-constrained Hartree-Fock-Bogoliubov wave functions with the Gogny interaction for the 32 Mg . We show that the more relevant degree of freedom is the quadrupole deformation. Minima of the ground state obtained in single-constrained calculations with this operator are hardly modified in double-constrained calculations insuring thereby the stability of the solution.

Titanium Isotopes

Hole states in scandium isotopes are investigated by coupling a d3/2 hole to low-lying states of the neighboring titanium isotopes. Titanium wave functions are obtained by angular momentum projection from 1f2p-shell Hartree–Fock intrinsic states, and diagonalizations are carried out using the Gillet and Sanderson particle–hole interaction. The binding energies of the 3/2 + states in 43Sc, 45Sc, and 47Sc are well reproduced, as is the spacing between higher-spin levels of the K = 3/2 bands, and the polarization of the titanium cores has approximately the magnitude needed to account for the long M2 lifetimes. The model fails to give any low-lying hole states in 44Sc, but a calculation of spectroscopic factors does account for the absence of observable l = 2 strength below 1.6 MeV in the 43Ca(3He,d)44Sc reaction.

The K-mixing effect is investigated for triaxial deformation through the angular momentum projection technique. The mathematical nature of the norm overlap kernels is discussed in terms of the Fourier analysis. A relation between the signature symmetry and the K quantum number is discussed. A non-cranked Hartree-Fock state is shown to be a K=0 dominating state. The spread of the K distribution happens in a symmetrical manner and the K-mixing is enhanced as triaxial deformation is enlarged. On the contrary, the J=0 component is contained only slightly against a naive expectation.

Transition Amplitudes

The transition amplitudes for direct reaction inelastic proton scattering from nuclei are formulated using target spectroscopy given by angular momentum projection from axially symmetric minimal energy Hartree-Fock intrinsic states of N = Z nuclei. Applications to the scatterings from 20Neare made, from which the importance of virtual excitations of giant resonances is evident.
