提出了一种在离子束冷却聚束器中选择性地增强离子亚稳态布居的新的光抽运方法。该技术允许以前无法访问的激光光谱学的元素的研究，并已在这里应用到铌的研究。研究了模型无关的均方电荷半径和核矩，以覆盖壳层闭合和形变突然发生的区域。观察到均方电荷半径的增加小于Y，在此之前和之后观察到相当程度的柔软性。
A new method of optical pumping in an ion beam cooler buncher has been developed to selectively enhance ionic metastable state populations. The technique permits the study of elements previously inaccessible to laser spectroscopy and has been applied here to the study of Nb. Model independent mean-square charge radii and nuclear moments have been studied forto cover the region of theshell closure andsudden onset of deformation. The increase in mean-square charge radius is observed to be less than that for Y, with a substantial degree ofsoftness observed before and after.
