Abstract

This paper presents a review of studies on the spatial structure of light exotic nuclei performed by the PNPI-GSI collaboration. A series of experiments has been carried out in beams of exotic nuclei with an energy of 0.7 GeV/nucleon at the Helmholtz Center for Heavy Ion Research (GSI, Darmstadt), in which the differential cross sections for proton–nucleus small-angle scattering in inverse kinematics have been measured using the ionization spectrometer IKAR developed at PNPI. An analysis of the measured cross sections has allowed us to determine the nuclear matter distributions in the studied nuclei of the He, Li, Be, B, and C isotopes and also to determine the halo sizes in ⁶He, ¹¹Li, ¹⁴Be, ⁸B, and ¹⁵C nuclei.

摘要

本文回顾了由 PNPI-GSI 合作进行的关于轻外来原子核空间结构的研究。亥姆霍兹重离子研究中心 (GSI, Darmstadt) 对能量为 0.7 GeV/核子的奇异核束进行了一系列实验，其中质子 - 核小角散射的微分截面使用 PNPI 开发的电离光谱仪 IKAR 测量了逆运动学。对测量横截面的分析使我们能够确定所研究的 He、Li、Be、B 和 C 同位素核中的核物质分布，并确定⁶ He、¹¹ Li、¹⁴ Be、⁸ B和¹⁵C 核。
