THE SPIN OF THE 3.70-MEV LEVEL IN Al25
Journal Article

· Canadian Journal of Physics
The 3.70-Mev level in Al/sup 25/ was studied by means of the reaction Mg/ sup 24/(p, gamma )Al/sup 25/ at the 1.49-Mev resonance. Direct angular distribution measurements of the de-excitation gamma radiation support the spin assignment of 7/2/sup -/ for this level. An E2/Ml amplitude mixing ratio of -- 0.55 plus or minus 0.2 is found for the 1.79-Mev de-excitation radiation from the fourth excited state to the ground state of Al/sup 25/. The ratio of the reduced transition probability of the E2 radiation from the 1.79-Mev level to the first excited state is shown to be approximates 30 times that to the ground state. This result provides further confirmation of rotational band structure in Al/sup 25/ since the collective model predicts such an enhancement of E2 transitions between rotational bands whereas cross-band transitions are not expected to be enhanced.
