Abstract
The reduced transition probabilities from an electric quadrupole B(E2) and reduced transition probabilities from a magnetic dipole B(M1) between the ground state and the first excited state have been calculated for the 3He(α,γ)7Be, 8Be(α,γ)12C and 12C(α,γ)16O radiative capture reactions with the M3Y potential. These reactions are important in stellar evolution. The calculated B(M1) and B(E2) for 7Be nuclei are found to be 1.082 × 10−3 e2 fm2 and 1.921 e2 fm4 from transitions 3/2− to 1/2−, respectively. The obtained values for reduced transition probabilities B(E2) for the 12C and 16O nuclei from transitions 0+ to 2+ are 12.54 e2 fm4 and 14.18 e2 fm4, respectively. The results are in satisfactory agreement with available experimental data.
