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.
