Study of Natb(3he,P) Reactions Cross Sections Using a Novel Setup for 3he-Nra Micro Analyses

Abstract

In the present work experimentally determined differential cross sections of the reactions 10B(3He, p1)12C, 11B(3He, p0,1,2,3)13C and 11B(3He, d0)12C are reported. The measurements cover the 2 - 3 MeV energy range, for 5 detection angles of θ = 137°, 141°, 146°, 152°, 158°. A novel experimental setup was designed for this purpose and installed at the Dual Microprobe end-station of the Ruđer Bošković Institute (RBI) in Zagreb, Croatia. It involves an annular strip charged particle silicon detector with a large solid angle, enabling a relatively fast acquisition process without significant increase in the angular uncertainty. The obtained cross sections were benchmarked with a thick amorphous boron target in a different experimental setup at RBI, as well as at the scattering chamber setup of the RUBION accelerator facility in Bochum, Germany.
