摘要:

本文简要介绍了用放射性核束高分辨率研究核子转移反应的一般实验技术,以及用新的TIARA装置获得的第一批新的物理结果。TIARA的第一个结果是24 Ne(d,p)25 Ne反应的结果,用来自GANIL的SPIRAL设施的100,000 pps的纯放射性核束进行逆运动学研究。反应探测的中子轨道的能量非常丰富的中子在这个质量区域的核和结果突出的N=16幻数的中子和相关的消失的N=20中子幻数非常丰富的氖同位素的出现。

英文摘要:

A general experimental technique for high resolution studies of nucleon transfer reactions using radioactive beams is briefly described, together with the first new physics results that have been obtained with the new TIARA array. These first results from TIARA are for the reaction 24Ne(d,p)25Ne, studied in inverse kinematics with a pure radioactive beam of 100,000 pps from the SPIRAL facility at GANIL. The reaction probes the energies of neutron orbitals relevant to very neutron rich nuclei in this mass region and the results highlight the emergence of the N=16 magic number for neutrons and the associated disappearance of the N=20 neutron magic number for the very neutron rich neon isotopes.
