In the present work experimentally determined differential cross sections of the reactions 10B(3He, p1,3)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.

使用新型 3He-NRA 微量分析装置研究 natB（3He， p） 反应截面


在本工作中，实验确定了反应 10B（3He， p1,3）12C、11B（3He， p0,1,2,3）13C 和 11B（3He， d0）12C 的差异截面。测量涵盖 2–3 MeV 能量范围，适用于 θ = 137°、141°、146°、152°、158° 的 5 个检测角度。为此目的设计了一种新颖的实验装置，并安装在克罗地亚萨格勒布的 Ruđer Bošković 研究所 （RBI） 的双微探针终端站。它涉及一个具有大立体角的环形带状带电粒子硅探测器，可实现相对较快的采集过程，而不会显著增加角度不确定性。在 RBI 的不同实验装置以及德国波鸿 RUBION 加速器设施的散射室装置中，用厚的非晶硼靶材对获得的横截面进行了基准测试。
