摘要

6Li(p,3He)4He反应的微分截面在5个探测角（130°至170°，步长10°）下测定，质子能量范围从140 keV到1000 keV，具有可变的能量步长。对于横截面测量，使用了两个不同的LiF靶，而对于反向散射粒子的检测，三个硅表面势垒（SSB）探测器放置在130°，140°和160°的角度，两个钝化植入平面硅（PIPS）探测器放置在150°和170°的角度。为了验证这项工作的不同截面，还进行了独立的基准测试实验。所得结果与文献中已有的结果进行了比较。这项工作的测量值被发现与文献中的一些现有数据很好地一致。然而，在几个能量区域，观察到与其他数据集的重要差异。

Study of the 6Li(p,3He)4He reaction, in the low energy range, suitable for NRA purposes

Differential cross sections of the ⁶Li(p,³He)⁴He reaction were determined at five detection angles (130° to 170°, with a 10° step), for proton energies ranging from 140 keV up to 1000 keV, with a variable energy step. For the cross-section measurements two different LiF targets were used, while for the detection of the backscattered particles, three Silicon Surface Barrier (SSB) detectors were placed at the angles of 130°, 140° and 160° and two Passivated Implanted Planar Silicon (PIPS) detectors at 150° and 170°. Independent benchmarking experiments were also performed, in order to validate the differential cross sections of this work. The obtained results are compared with existing ones available in the literature. The measured values of this work are found to be in good agreement with some existing data from the literature. However, important discrepancies with other datasets were observed, in several energy regions.

期刊介绍： Section B of Nuclear Instruments and Methods in Physics Research covers all aspects of the interaction of energetic beams with atoms, molecules and aggregate forms of matter. This includes ion beam analysis and ion beam modification of materials as well as basic data of importance for these studies. Topics of general interest include: atomic collisions in solids, particle channelling, all aspects of collision cascades, the modification of materials by energetic beams, ion implantation, irradiation - induced changes in materials, the physics and chemistry of beam interactions and the analysis of materials by all forms of energetic radiation. Modification by ion, laser and electron beams for the study of electronic materials, metals, ceramics, insulators, polymers and other important and new materials systems are included. Related studies, such as the application of ion beam analysis to biological, archaeological and geological samples as well as applications to solve problems in planetary science are also welcome. Energetic beams of interest include atomic and molecular ions, neutrons, positrons and muons, plasmas directed at surfaces, electron and photon beams, including laser treated surfaces and studies of solids by photon radiation from rotating anodes, synchrotrons, etc. In addition, the interaction between various forms of radiation and radiation-induced deposition processes are relevant.
