Study of cascade dynamics of kaonic nitrogen atom by Monte-Carlo method

Cascade dynamics of kaonic nitrogen atom (K-N) in a gaseous target was simulated using a simple model. In this model the radiative transitions, internal Auger, K-electron refilling, nuclear absorption, and kaon decay processes were included. The effect of the K-electron refilling process on some of quantities of cascade dynamics such as X-ray yields, the averaged K-electron shell number, fraction of the nuclear absorption and the averaged de-excitation time was studied by Monte-Carlo method. Using a fitting method, the range of K-electron refilling rate was predicted between 0.1 to 0.6 ps-1. This result is in agreement with the theoretical value.
