摘要

本研究考察了200 MeV/u 40Ar离子束辐照铜靶中大于65Cu的γ -发射核的产生和分布。伽马谱显示，质量数在67 ~ 101之间的伽马发射核集中在40Ar离子范围附近。观察到核素分布的质心随着质量的增加而更深地移动，这与40Ar离子在其路径接近终点时减少的动能一致。这些结果表明，测量的诱导重核素活度曲线可以用来估计弹丸在目标中的距离。

Experimental study of production of nuclei heavier than 65Cu in a copper target bombarded with 200 MeV/u 40Ar ions

This study examines the production and distribution of gamma-emitting nuclei heavier than ⁶⁵Cu in a copper target irradiated with a 200 MeV/u ⁴⁰Ar ion beam. Gamma spectra revealed that the gamma-emitting nuclei with mass numbers from 67 to 101 were concentrated near the range of the 40Ar ions. The centroids of nuclide distributions were observed to shift deeper with increasing mass, aligning with the reduced kinetic energy of the ⁴⁰Ar ions near the end of their path. These results demonstrate that the measured profiles of induced heavy-nuclide activity can be used to estimate projectile range in the target.

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.
