Abstract

For the first time, in-gas-cell laser spectroscopy study of the (57,59,63,65)Cu isotopes has been performed using the 244.164 nm optical transition from the atomic ground state of copper. The nuclear magnetic dipole moments for (57,59,65)Cu relative to that of (63)Cu have been extracted. The new value for (57)Cu of mu((57)Cu) = +2.582(7)mu(N) is in strong disagreement with the previous literature value but in good agreement with recent theoretical and systematic predictions.

摘要

首次利用铜原子基态的244.164nm光学跃迁对（57、59、63、65）铜同位素进行了气室激光光谱研究。提取了（57、59、65）铜相对于（63）铜的核磁偶极矩。μ（57Cu）=+2.582（7）μN这一（57）铜的新值与先前文献值存在强烈分歧，但与近期理论和系统预测结果吻合良好。
