Investigation of the gamma decay of excited states in25Al

The gamma decay of the low-lying energy levels (E _x <4MeV) in²⁵Al has been studied through the²⁴Mg(p, γ)²⁵Al reaction using seven resonances in the proton energy rangeE _p +200?1700 keV. Ge(Li) detectors and isotopically separated targets have been used. Energies and branching ratios of several excited states have been measured. TheQ-value of the reaction was determined to be 2271.3±0.8 keV. Lifetimes, investigated by the Doppler-shift attenuation method and γ-ray angular distributions have been determined using theE _p +823, 1201, 1490 and 1660 keV resonances of the²⁴Mg(p, γ)²⁵Al reaction.
