ar X iv : n uc l - th / 0 11 10 76 v 2 2 J an 2 00 2 1 TWO - POTENTIAL APPROACH TO MULTI - DIMENSIONAL TUNNELING

We consider tunneling to the continuum in a multi-dimensional potential. It is demonstrate that this problem can be treated as two separate problems: a) a bound state and b) a non-resonance scattering problem, by a proper splitting of the potential into two components. Finally we obtain the resonance energy and the partial tunneling widths in terms of the bound and the scattering state wave fun...

We have performed shell-model calculations starting from the CD-Bonn free nucleon-nucleon (N N) potential and making use of a new approach for the calculation of the effective interaction. This consists in deriving from the N N potential a low-momentum effective potential V low−k , defined within a given cutoff momentum Λ. Being a smooth potential it can be used directly in nuclear structure ca...

The orientation of the angular momentum vector with respect to the triaxial density distribution selects a left-handed or right-handed system principal axes. This breaking of chiral symmetry manifests itself as pairs of nearly identical ∆I = 1-bands. The chiral structures combine high-j particles and high-j holes with a triaxial rotor. Tilted axis cranking calculations predict the existence of ...
