All levels between 5.2 and 6.1 MeV in 25Mg have been studied using the reaction 25Mg(p,p′γ). Inelastically scattered protons were detected in an annular surface barrier detector located at 180°; coincidence gamma-ray spectra were obtained at Ge(Li) detector angles of 90, 45, and 135°. Level energies were determined from unshifted gamma-ray energies recorded in the 90° spectra. Lifetimes were obtained from the attenuated Doppler shift of gamma-ray energies recorded in spectra taken at forward and backward angles. Branching ratios were deduced from the combined data of all three angles. The identification of levels as members of rotational bands is discussed, and transition strengths deduced from the present measurements are compared with predictions of the simple rotational model. In particular, evidence is presented for the identification of a level at 5535 keV as the 11/2 member of the ground state band, levels at 5522 and 5794 keV as the 5/2 and 11/2 members of the Kπ = 1/2− band, and a level at 6040 keV as the 11/2 member of a Kπ = 9/2+ band.
