Lifetimes and decay modes of low-lying levels in ²⁶Mg and ²⁶Al

Abstract

Several bound states with excitation energy up to 7 MeV were studied in 26 Mg, using the 26 Mg(p, p′γ) reaction. The attenuated Doppler shift of the de excitation gamma rays was observed with a Ge(Li) spectrometer. The extracted lifetime estimates and branching ratios for 15 excited states suggest that the rotational bands, built on different intrinsic states, are mixed considerably. Incidental information on lifetimes and decay properties of states in 26 Al is also presented.
