Angular distributions and excitation functions of protons from the reaction Mg25 (d, p)Mg26 leading to the 1.83– and 2.97– MeV state of Mg26, have been in vestigated in the deuteron energy range from 1.55– to 3.00– MeV. The yield of the protons leading to the ground state were so small that this group was not measured. The results of angular distributions were compared with the deuteron stripping theory, and a qualitative agreement for the second excited state group at the deuteron energies above 2.5 MeV, was obtained in the forward directions, but not for the first excited state group and also in the backward directions for each groups.<BR>The angular distributions of the first excited state group at the deuteron energies above 2.44 MeV, could be fitted to Bhatia’s formula with two ln-values of 0 and 2. Both angular distributions include considerably isotropic part, and show a competition between the deuteron stripping process and the compound nucleus formation. Also, the results of excitation functions for total cross section were compared with the statistical theory and a fairly good agreement was obtained with the interaction radius of (1.21+1.3·A1⁄3)×10−13 cm. Furthermore, a considerably small yield of this reaction seems to show that Coulomb effects play an important role in this lower energy range.
