摘要
In 2016,the Atomic&Molecular Spectroscopy Group made progress on spectroscopy study in ion-atom collisions,data analysis of hollow atoms,and preparation of new experiments.X-ray spectra of K-shell hollow krypton atoms produced in single collisions with 52– 197 MeV/u Xe54+ions,measured at the CSRe internal,are analyzed.Energy shifts of the Kα1,2^S,and Kβ1,3^S transitions are obtained.Thus,the average number of the spectator L-vacancies presented during the X-ray emission is deduced.
