We show some results of systematic calculation on electric dipole responses of even-even nuclei, employing a Hartree-Fock plus RPA approach. For an easy implementation of the fully self-consistent calculation, a finite amplitude method which we proposed recently is employed. We show a systematic comparison of calculated peak energies of giant dipole resonances and an importance of low-angular momentum orbit for emergence of pygmy dipole resonances.

We obtain Thomas–Fermi solutions for nuclei in the mass range [Formula: see text]. Solutions for a given nucleus are obtained from angular momentum zero to the maximum value at which the nucleus breaks up. On one hand, we can establish contact with the liquid-drop model; on the other hand since Thomas–Fermi theory can be regarded as an approximation to Hartree-Fock theory and does use an underlying force (the same force can be used in Hartree–Fock theory), it is also instructive to compare results with the quantum cranking calculations carried out by other researchers. It appears that for low-mass nuclei quantum effects make the two results very different even at high spins but for medium-mass nuclei there are similarities that are seen at high-spin states. Rather large deformations are obtained at high-spin states but the magnitudes are sensitive to the actual force used. We present graphs indicating the change of shape in the Q – γ plane as angular momentum is cranked up.

We present a generalization of the Extended Thomas Fermi (ETF) theory to fermionic systems at finite temperature and finite angular momentum. In fact the present approach is more general in the sense that it is able to treat an excited system of fermions subject to an external vector field which in the case of nuclear rotations, developed more extensively here, is simply [Formula: see text].

It is possible to reproduce the entire results of Pekeris et al. of different atomic parameters for the He atom by introducing (ll) type correlation in a self consistent variation perturbation procedure using the Hartree-Fock (HF) wavefunction as the zero-order wavefunction
