Description
Summary: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 7 Be in the 3 He 4 He cluster model with forbidden states, the astrophysical S -factor for the radiative capture reaction 3 He( 4 He,γ) 7 Be has been calculated from 10 keV. The result obtained, S (23 keV) = 0.561 keV·b, reproduces the latest experimental data at 23 keV. The calculated and parametrized reaction rate is compared with some known results in the range of temperatures from 0.05 to 5  T 9 .
