Annotation	Nuclear (p,alpha) reactions destroying the so-called "light-elements" lithium, beryllium and boron have been largely studied in the past mainly because their role in understanding some astrophysical phenomena, i.e. mixing-phenomena occurring in young F-G stars [1]. Such mechanisms transport the surface material down to the region close to the nuclear destruction zone, where typical temperatures of the order of similar to 10(6) K are reached. The corresponding Gamow energy E-0=1.22 (Z(x)(2)Z(X)(2)T(6)(2))(1/3) [2] is about similar to 10 keV if one considers the "boron-case" and replaces in the previous formula Z(x) = 1, Z(X) = 5 and T-6 = 5. Direct measurements of the two B-11(p,alpha(0))Be-8 and B-10(p,alpha)Be-7 reactions in correspondence of this energy region are difficult to perform mainly because the combined effects of Coulomb barrier penetrability and electron screening [3].
