Applications of Continuum Shell Model
The nuclear many-body problem at the limits of stability is considered in the framework of the Continuum Shell Model that allows a unified description of intrinsic structure and reactions. Technical details behind the method are highlighted and practical applications combining the reaction and structure pictures are presented.
متن کاملNo-Core Shell Model and Continuum Spectrum States of Light Nuclei
Shell model is a conventional tool for nuclear structure studies. Some states obtained in such studies belong to the continuum nuclear spectrum, i.e. their energies are above nuclear dissociation thresholds. These energies are conventionally associated with the energies of resonances in respective nuclear systems that is justified only in the case of narrow resonances. In this contribution, we ...
متن کاملPionic decay of L hypernuclei in a continuum shell model
The pionic decay of L hypernuclei has received attention in the past both from the experimental @1–7# and theoretical @8–22# points of view ~for a recent review see Ref. @23#!. It is well known that the mesonic decay is largely suppressed by Pauli blocking, although the consideration of proper pion distorted waves @13,16,20# weakens the effect of the Pauli blocking considerably. On the other ha...
متن کاملPionic decay of Λ Hypernuclei in a Continuum Shell Model
We evaluate pionic decay widths of Λ hypernuclei using a shell model for, both the nuclear bound and the continuum nucleon wave functions in the final state, and distorted waves for the outgoing pion. An excellent agreement with the recent KEK measurement of π −-decay widths of 12 Λ C and 28 Λ Si is found. Besides, results for 56 Λ Fe are consistent with the existing upper bound.
متن کاملRadiative pion capture in nuclei: a continuum shell–model approach
The radiative pion capture process in nuclei is approached by using a continuum shell–model description of the nucleus, together with a phenomenological treatment of the two particle–two hole effects. It is found that these effects play an important role to reproduce the observed experimental photon energy distribution. This distribution as well as the integrated one depends significantly on th...
