Abstract

The measurement of the ¹¹⁶Sn(¹⁸O, ¹⁸Ne)¹¹⁶Cd double charge exchange reaction cross section at very forward angles was performed for the first time at INFN-LNS using the MAGNEX magnetic spectrometer. This study, carried out at 276 MeV beam energy, provides a cross section of 34 nb ([9, 44] nb at 95% confidence level), confirming the tiny values recently obtained for the same reaction in other nuclides. This result has a major impact on the forthcoming systematic investigation of

0 ν β β

decay candidates carried out by the NUMEN project, since it allows to properly tailor future experiments with high-intensity beams. The ultimate goal of this exploration is to experimentally access information about nuclear matrix elements relevant to the

0 ν β β

decay rate.

在 276 兆电子伏测量 116Sn（18O, 18Ne）116Cd 双电荷交换反应

在 INFN-LNS 使用 MAGNEX 磁谱仪首次测量了极前角的 116Sn(18O,18Ne)116Cd 双电荷交换反应截面。这项研究是在 276 MeV 射束能量下进行的，得出了 34 nb 的横截面（95% 置信度下为 [9, 44] nb），证实了最近在其他核素的相同反应中获得的极小值。这一结果对 NUMEN 项目即将开展的 0νββ 衰变候选物质的系统研究具有重大影响，因为它可以适当调整未来的高强度束实验。这一探索的最终目标是通过实验获取与 0νββ 衰变率相关的核矩阵元素信息。

期刊介绍： Results in Physics is an open access journal offering authors the opportunity to publish in all fundamental and interdisciplinary areas of physics, materials science, and applied physics. Papers of a theoretical, computational, and experimental nature are all welcome. Results in Physics accepts papers that are scientifically sound, technically correct and provide valuable new knowledge to the physics community. Topics such as three-dimensional flow and magnetohydrodynamics are not within the scope of Results in Physics. Results in Physics welcomes three types of papers: 1. Full research papers 2. Microarticles: very short papers, no longer than two pages. They may consist of a single, but well-described piece of information, such as: - Data and/or a plot plus a description - Description of a new method or instrumentation - Negative results - Concept or design study 3. Letters to the Editor: Letters discussing a recent article published in Results in Physics are welcome. These are objective, constructive, or educational critiques of papers published in Results in Physics. Accepted letters will be sent to the author of the original paper for a response. Each letter and response is published together. Letters should be received within 8 weeks of the article''s publication. They should not exceed 750 words of text and 10 references.
