An Investigation of (d, p) Stripping Reactions II: Results for the Isotopes of Magnesium

Angular distribution measurements have been carried out on a number of proton groups from the bombardment with 8 MeV deuterons of targets of natural magnesium and of 25MgO and 26MgO. Spins and parities have been assigned to various states of the product nuclei on the basis of the theory of the stripping process. These are given herewith, the excitation energy of each state in MeV being followed by the possible spin values and the parity in brackets: 25Mg: ground state (5/2, 3/2+), 0.582(1/2+), 0.976(5/2, 3/2+), 1.957(5/2, 3/2+), 3.405(3/2, 1/2-). 26Mg: 1.825(3, 2+ and 5, 4...0+), 2.972(3, 2+), 3.969(3, 2+), 4.353(3, 2+), 6.147(3, 2+). 27Mg: ground state (1/2+), 0.887(5/2, 3/2+), 3.50(1/2+). The following new energy levels have been observed: 25Mg: 4.62 ± 0.05, 5.05 ± 0.08, 5.49 ± 0.05 and 6.40 ± 0.05 MeV. 26Mg: 7.29 ± 0.06 and 8.28 ± 0.06 MeV. 27Mg: 3.50 ± 0.05 MeV.
