Abstract

In this study, the aim has been the interpretation of the measured x-ray spectrum for kaonic atoms (Z>2) in various elements and compounds. Initially, kaon capture probability in the compounds is calculated and compared by different atomic models. By using Mont-Carlo method, the atomic cascade dynamic of atoms is simulated and the yield of each transition is obtained. By using the fitting method for each atom, the optimum parameters of the two models for the initial angular momentum distribution are extracted. The Z-dependence of these parameters confirms the Condo' hypothesis concern regarding the correlation between the size of atom and the initial angular moment of atom that lead to the periodic behavior of X-ray yields. By comparing the yields and its ratios with the measured values, a good agreement in the most of cases is obtained.
