Inclusive $\gamma$ spectra from the ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$+${}_{}{}^{24}{}_{}{}^{}\mathrm{Mg}$ interaction have been measured using from 45 up to 105 MeV ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$ beams. Experimental mass and charge spectra are compared with statistical model calculations. Total reaction and fusion cross sections are extracted. The optical, Glas and Mosel, and Bass model calculations are presented and compared with the data. The limitation of the fusion cross section by the statistical yrast line is also discussed.
