Kinetics of Atomic Cascade in Light Exotic Atoms

Recent results on the kinetics of atomic cascade in hydrogen-like exotic atoms are reviewed. The problem of kinetic energy distribution during the atomic cascade is studied in detail with a new Monte Carlo kinetics code. For the first time, nuclear absorption in the light hadronic atoms is treated consistently with elastic scattering and Stark mixing processes by using the collisional cross sections calculated in the close-coupling approximation [1]. The rates for the high n states are calculated with the classical-trajectory Monte Carlo method. Evidence for cascade processes beyond the extended standard cascade model is discussed.
