Étude du noyau 28Mg par la réaction 26Mg(t, pγ)28Mg

摘要: Resume Angular correlation and Doppler shift attenuation methods were used to measure γ-ray branching ratios, spins, mixing ratios lifetimes of 28 Mg excited states between 4.9 5.8 MeV, produced in the 26 Mg(t, pγ) reaction at E t = 2.54, 2.90 3.20 MeV. Gamma rays detected coincidence with proton groups, observed 0° 180° for angular measurements, DSA measurements. The results excitation energies (keV), J π τ m (ps) are: 5171.9 ± 0.5, 3 − , 0.18 0.02; 5192.7 0.7, 1 + 0.30 0.05. Two previously unreported levels identified 4560.8 0.8 keV ( 1) 5184.6 0.7 keV. Other have been 5469.1 5672.8 2 ). spectrum is compared other experimental recent theoretical predictions.
