Abstract
Mean lifetimes of levels in the mirror nuclei 29Si and 29P have been measured using the Doppler-shift-attenuation (DSA) method and the reactions 15N( 16O, np) 29Si and 28Si(p, γ) 29P. The lifetime values or limits were determined for 14 bound levels in 29Si below the excitation energy of 9 MeV and for 4 levels in 29P below the excitation energy of 4.1 MeV. The lifetimes of 5 levels in 29Si are reported for the first time. In order to provide effective stopping of recoils, the targets were prepared by implanting 15N and 28Si into Ta backings. The Monte Carlo method and experimental stopping power were used in the DSA analysis. The experimental transition strengths are compared with recent shell model calculations.
