A formulation of the equations of motion phonon method (EMPM) suited for hypernuclei is outlined and illustrated through an application to B 12 . A self-consistent calculation using realistic modern potentials is performed using a multiphonon basis which enables us to couple the ?-particle-proton-hole (p? - h) Tamm-Dancoff (TD?) states to the excitations of the nuclear core. The impact of such a coupling on the energy levels and on the electroproduction cross section of B 12 suggests that complex configurations accounting for the excitation of the nuclear core are needed for approaching the experimental data.

Abstract
A formulation of the equations of motion phonon method (EMPM) suited for hypernuclei is outlined and illustrated through an application to B 12 . A self-consistent calculation using realistic modern potentials is performed using a multiphonon basis which enables us to couple the ?-particle-proton-hole (p? - h) Tamm-Dancoff (TD?) states to the excitations of the nuclear core. The impact of such a coupling on the energy levels and on the electroproduction cross section of B 12 suggests that complex configurations accounting for the excitation of the nuclear core are needed for approaching the experimental data.File in questo prodotto:
