Nuclear Energy Levels ofAl27

Abstract

Twenty energy levels in ${\mathrm{Al}}^{27}$ have been found by the magnetic analysis of inelastically scattered protons at 90° from thin targets of aluminum. An analyzed beam of 8.0-Mev protons was utilized for the bombardment. Tentative values for the levels found are 0.844, 1.016, 2.259, 2.782, 3.046, 3.736, 4.018, 4.115, 4.473, 4.575, 4.647, 4.875, 4.996, 5.107, 5.220, 5.341, 5.501, 5.565, 5.620, 5.736 Mev. A broad alpha-particle group from the ${\mathrm{Al}}^{27}(p,\alpha ){\mathrm{Mg}}^{24}$ reaction corresponding to an excited state of ${\mathrm{Mg}}^{24}$ was also observed and is believed to be complex.
