β-band excitation in inelastic hadron scattering and the mixing of the breathing mode into the low-lying β-vibrations

Abstract

The excitation of the 24Mg β-band 0+ and 2+ states at 6.43 MeV and 7.35 MeV, respectively, in inelastic hadron scattering has been considered in the collective model where coupling of these states of the states of the ground state band is via a s-vibration coupled to the static deformation. It is found that coupled channel effects on the 0+ state excitation are rather important and moreover the excitation of the 0+ state can be satisfactorily explained only if a monopole breathing mode form factor is included in addition to the monopole β-vibration form factor.
