Measurement of the magnetic moment of 110Sn(21+) for determining its nuclear structure

在核结构物理学中，锡同位素是核子-核子相互作用和由此产生的壳层结构的最重要代表。总共有10个稳定的同位素展示了神奇质子数Z=50的独特的稳定能力。对所有稳定同位素的E_2跃迁强度和21+态磁矩的系统测量表明，核结构比人们在广泛的壳层模型计算基础上预期的要复杂得多。这一特征特别体现在测量的不足中子的106,108,110锡同位素的增强的B(E_2)值以及最近发现的116锡的最小值上。鉴于这些数据，我们计划测量110Sn(21+)的g因子，以便更深入地了解这个原子核的核子结构。

The Sn isotopes belong in the nuclear structure physics to the most important representatives of the nucleon-nucleon interaction and the resulting shell structures. A total number of 10 stable isotopes demonstrates the unique power of stability of the magic proton number Z=50. Systematic measurements of the E2 transition strengths and the magnetic moments of the 21+ states of all stable isotopes indicate that the nuclear structure is more complicated than one would expect on the basis of extensive shell model calculations. This feature is particularly expressed by the measured enhanced B(E2) values of the neutron-deficient 106,108,110Sn isotopes as well by the minimum recently found for 116Sn. In view of these data we are planning to measure the g-factor of 110Sn(21+) in order to obtain more insight into the nucleon structure of this nucleus.
