Potential cluster calculations for the astrophysical S-factor and reaction rate of the radiative 3He(4He,γ)7Be capture

Abstract

In the frame of a modified potential cluster model based on the classification of orbital states according to Young diagrams and revised interaction potential parameters for the bound states of 7Be in the 3He4He cluster model with forbidden states, the astrophysical S-factor for the radiative capture reaction 3He(4He,γ)7Be has been calculated from 10\xa0keV. The result obtained, S(23\xa0keV)\u2009=\u20090.561\xa0keV·b, reproduces the latest experimental data at 23\xa0keV. The calculated and parametrized reaction rate is compared with some known results in the range of temperatures from 0.05 to 5\u2009T9.
