Energy shifts of the K{\\alpha}_1,2^s, K{\\alpha}_1,2^(h,s), and K\\b{eta}_1,3^s transitions are obtained. Thus, the average number of the spectator L-vacancies presented during the x-ray emission is deduced. From the relative intensities of the K{\\alpha}_1,2^s and K{\\alpha}_1,2^(h,s) transitions, the ratio of K-shell hollow krypton to singly K-shell ionized atoms is determined to be 14 - 24%.
