In the present work the radiative capture reaction 3H(α, γ)7Li has been investigated. The astrophysical S-factor and the branching ratio of the reaction have been calculated within a microscopic approach – the algebraic version of the resonating-group model. The lowest compatible with the Pauli exclusion principle wave functions of the translation-invariant oscillator shell model are adopted as the internal wave functions of the colliding clusters. The modified Hasegawa–Nagata NN-potential was employed in the calculations. The results are in good agreement with the experimental data.
