Abstract

The resonance reaction25Mg(p, γ)26Al in the energy rangeE p =300–400 keV was used to populate high-lying bound states in the self-conjugate nucleus26Al. The existence of three resonances atE p =304, 316 and 388 keV was verified, the spins of the ones at 316 and 388 keV were found to be 3− and 2+, respectively. The spin of the bound level at 4,547 keV level was fixed to beJ π=2+. Several strong isovector Ml transitions were observed, which led toT=1 assignments for the levels atE x =4,191, 4,547, 4,599, 5,141 and 5,542 keV. The results for excitation energies and values ofJ π,T together with previous experimental and theoretical data on26Al and the neighboring |T z |=1 nuclei26Mg and26Si are discussed in the framework of the isospin model.
