De-excitation of $K$ -shell hollow atoms with $12 \leq Z \leq 20$ : transition rates and branching ratios

Karol Kozioł, Jacek Rzadkiewicz

Investigating $K$ -shell hollow atom spectra enhances our understanding of femtosecond phenomena in atomic physics, chemistry, and biology. Synchrotron measurements of two-electron…
