Reaction-mechanisms for astrophysically relevant nuckear processes
(1993-07)
The different reaction mechanisms and models applied to nuclear reactions at thermonuclear energies are discussed. As an example we consider the reaction Li-8(alpha,n)B-11.
The astrophysical S-factor of the reaction Be-7(P,gamma)B-8 in the direct capture model
(1993)
The astrophysical S-factor for the reaction Be-7(p, gamma)B-8 up to an energy of 2 MeV (c.m.) and the capture cross section of Li-7(n, gamma)Li-8 up to 1 MeV (c.m.) are calculated using the Direct Capture model (DC). Both ...
Calculation of the He-3(He-3, 2p)He-4 AND H-3(H-3, 2N)He-4 astrophysical S-factor at low energies
(1992-08)
We have calculated the cross sections for the charge symmetric reactions He-3(He-3,2p)He-4 and He-3(He-3,2p)He-4 at sub-Coulomb energies in the potential model. Good agreement with the experimental data is obtained. The ...
Analysis of Li-8(alpha, n)B-11 below the Coulomb barrier in the potential model
(1992-04)
The reaction Li-8(alpha, n)B-11 is of interest in inhomogeneous big bang nucleosynthesis. A distorted wave Born approximation calculation employing folding potentials is presented for energies below the Coulomb barrier. ...
