摘要

本研究报告了实验测定的 10B(3He,p1,3)12C、11B(3He,p0,1,2,3)13C 和 11B(3He,d0)12C 反应的微分截面。测量覆盖 2-3 MeV 能量范围，5 个探测角分别为 θ = 137°、141°、146°、152°、158°。为此设计了一个新颖的实验装置，安装在克罗地亚萨格勒布鲁德尔-博什科维奇研究所（RBI）的双微探针终端站。它包括一个环形带电粒子硅探测器，具有较大的固角，能够在不显著增加角度不确定性的情况下实现相对较快的采集过程。所获得的横截面以 RBI 的不同实验装置中的厚无定形硼靶以及德国波鸿 RUBION 加速器设施的散射室装置为基准。

Study of natB(3He, p) reactions cross sections using a novel setup for 3He-NRA micro analyses

In the present work experimentally determined differential cross sections of the reactions ¹⁰B(³He, p_1,3)¹²C, ¹¹B(³He, p_0,1,2,3)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.

期刊介绍： Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
