摘要:
用中国原子能科学研究院HI 13串列加速器提供的 90和 130MeV的Br离子和束箔技术 ,研究了波长在 13— 2 9nm范围内Br的类Mg离子的光谱 .识别出 2 4条属于BrXXIV的“3,3”跃迁 ,即 3s2 ,3s3p ,3p2 ,3s3d和 3p3d组态之间的跃迁谱线 ,其中 19条以前未见报道 .基于实验跃迁谱线 ,19个观测能级得以确立 ,其中有 14个能级此前未见报道 .相对论Hartree Fock(HFR)方法的计算结果对所观测的能级进行了解释.The spectrum of Mg-like Br, Br XXIV is investigated by means of beam-foil technique. Bromine ions of 90 and 130 MeV energy from the HI-13 tandem accelerator are used, and the wavelength region 13-29 nm is investigated. In the spectra, 24 Br XXIV transitions within the n=3 complex, i.e. between the 3s 2, 3s3p, 3p 2, 3s3d and 3p3d configurations are identifies, among them 19 have not been reported before. Based on these transition lines 19 energy levels have been determined and 14 energy level...
Abstract:
The spectrum of Mg-like Br, Br XXIV is investigated by means of beam-foil technique. Bromine ions of 90 and 130 MeV energy from the HI-13 tandem accelerator are used, and the wavelength region 13-29 nm is investigated. In the spectra, 24 Br XXIV transitions within the n=3 complex, i.e. between the 3s 2, 3s3p, 3p 2, 3s3d and 3p3d configurations are identifies, among them 19 have not been reported before.
