A study of24Mg by inelastic electron scattering

Abstract

The excited states of 24Mg with excitation energies less than 14.0 MeV were studied by inelastic electron scattering in the momentum transfer range 0.4 to 1.14 fm-1. Ground state transition probabilities and transition radii were deduced for 9 known levels with excitation less than 11 MeV and evidence was obtained for a (2+, 4+) doublet at 10.352+or-0.024 MeV. In the excitation energy region 11.0 to 14.0 MeV three E2 and four E3 transitions were observed and their ground state widths were deduced. The known 2- states at 12.67 MeV and 13.37 MeV were found to have ground state widths of (1.4+or-0.5)*10-2 eV and (4.0+or-1.4)*10-2 eV respectively.
