The reactions $^{10}$B(p,$\alpha$)$^{7}$Be and $^{11}$B(p,$\alpha$)$^{8}$Be are studied at thermonuclear energies using DWBA calculations. For both reactions, transitions to the ground states and first excited states are investigated. In the case of $^{10}$B(p,$\alpha$)$^{7}$Be, a resonance at $E_{Res}=10$ keV can be consistently described in the potential model, thereby allowing the extension of the astrophysical $S$-factor data to very low energies. Strong interference with a resonance at…

A test of the zero-range DWBA method at astrophysical energies
Abstract.The DWBA method is tested through a comparison with a microscopic cluster model on the 13C (α, n) 16O reaction in the energy range E = 0-5MeV, relevant for nuclear astrophysics. The
The Trojan Horse Method application on the 10B(p,α0)7Be reaction cross section measurements
The 10 B(p,α 0 ) 7 Be reaction cross section has been measured in an wide energy range from 2.2 MeV down to 3 keV in a single experiment applying THM. Optimized experimental set-up ensured good
