| Popis: | Angular distributions and excitation functions of protons from the reaction Mg>s2/sup >(/p)Mg>s2/sup >,/eading to the 1.83- and 2.97-Mev states of Mg>s2/sup >,/re investigated in the deuteron energy range from 1.55 to 3.00 Mev. The yield of 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 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 group. The angular distributions of the first excited state group at deuteron energies above 2.44 Mev could be fitted to Bhatia's formula with two l/sub n/-values of 0 and 2. Both angular distributions include a considerable isotropic part and show a competition between deuteron stripping and compound nucleus formation. Also, the results of excitation functions for the 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- A>s1/sup >>)/ 10>s-/sup >> /. Furthermore, the small yield of this reaction seems to show that Coulomb effectsmore » play an important role in this lower energy range.« less |
