ASTROPHYSICAL FACTOR FOR THE RADIATIVE-CAPTURE REACTION ALPHA-]LI-6+GAMMA(D)

We consider the radiative capture process alpha+d-->Li-6+gamma at ener gies, E(c.m.)less than or equal to 300 keV, that are relevant for astr ophysical processes. Due to the peripheral character of the reaction, the overall normalization of the astrophysical factor S-24 is entirely governed by one quantity, the asymptotic normalization coefficient C- 01 for Li-6-->alpha+d. Using the recently well established value for t his constant C-01=2.3+/-0.12 fm(-1/2), we calculated S-24 taking into account both E1 and E2 contributions. Our recommended value for S-24 i s 2.57 MeV nb at the most effective energy for the capture reaction in astrophysical processes, E(c.m.)=70 keV, which gives a reaction rate 0.036 cm(3) mole(-1) s(-1) at the temperature 0.8x10(9) K. We found a significant energy dependence of S-24 at astrophysical energies. At en ergies of less than 110 keV, the E1 component dominates over the E2 co mponent. AtE(c.m.)=70 keV, the E1 contribution to the total transition is about 58%.
