摘要: Differential cross sections for proton scattering from the six lowest states of /sup 24/Mg have been measured at eleven energies 15 to 35 MeV. Optical model parameters with a constant geometry and linear dependence well depths deduced whole energy range. Coupled channel calculations asymmetric rotational describe satisfactorily inelastic data K/sup (/ = 0/sup +/ band while, in fits relative some members 2/sup band, disagreements found. (p,d,p') (p,p'',p') two-step effects considered; contributions 3/sup +//sub 2/(5.22 MeV) level last process show an agreement giant resonance strength distributions.
