Elastic and inelastic differential cross sections of protons scattered from /sup 24/Mg were measured for incident proton energies of 20.0, 25.0, 30.4, 34.9, 39.9, and 44.9 MeV. Angular distributions from 10/sup 0/ to 170/sup 0/ in the laboratory were obtained for seven states of /sup 24/Mg, namely: 0/sup +/ (0.00 MeV), 2/sup +/ (1.37 MeV), the sum of 4/sup +/ (4.12 MeV) and 2/sup +/ (4.24 MeV), 3/sup +/ (5.24 MeV), 4/sup +/ (6.01 MeV), and 0/sup +/ (6.43 MeV). These data, along with data from the literature in the energy range 17--185 MeV, were analyzed using optical model and coupled channels calculations. Using a rotational model, with triaxial deformation limited to terms in Y/sub 2,2/ and Y/sub 2,-2/, reasonable agreement with the data was obtained for all states except for the 3/sup +/ (5.24 MeV) and 4/sup +/ (6.01 MeV) states. The inclusion of terms of Y/sub 4,2/ and Y/sub 4,-2/ in the model improved the agreement with these two states considerably; but the 3/sup +/ (5.24 MeV) experimental data are still not accurately reproduced.
