-
摘要: 介绍了储存环高精度分子谱学研究的科学意义、 国内外研究现状和利用HIRFL-CSR开展该项研究的优势， 着重论证了HIRFL-CSR分子离子注入实验环的总体设计方案和技术方案。 通过在HIRFL-CSR实验环上增建一条分子离子注入线， 将实验环改造成能兼顾现有物理实验和大分子物理研究的综合性研究平台， 为分子离子复合离解研究提供良好的技术支撑。 特别是质量数大于70的分子离子， 能显著提高其能量分辨。 In the present paper， it is introduced the scientific background and the current status of the high precision spectroscopy of the molecular ions at cooler storage ring. The advantages to study the dissociative recombination(DR) processes using cooler storage ring CSRe are discussed. The physics design，the main parameters of the injection beam line and the injection of the molecular ions into the CSRe and the key techniques are described in detail. With a new injection beam line，HIRFL-CSRe will be reconstructed to a multidiscipline research platform，offering good opportunities for the study of DR processes of molecular ions，especially for that of the molecular ions of m>70 amu with much improved resolution.Abstract: In the present paper， it is introduced the scientific background and the current status of the high precision spectroscopy of the molecular ions at cooler storage ring.
