Abstract
The kinetic energy distributions of μ − p and π − p atoms at a time of the radiative np→1s transitions and chargeexchange reaction in case of π − p have been studied in the improved version of extended standard cascade model ESCM Ab initio quantummechanical calculations of the differential and integral cross sections of the elastic scattering Stark transitions Coulomb deexcitation CD and induced absorption in case of pionic hydrogen have been performed in a framework of the closecoupling approach for the states of exotic atoms with nleqslant 8 and relative motion energies E geqslant 00001 eV The calculated Xray yields and kinetic energy distributions are in good agreement with the known experimental data The initial n l Edistributions of the exotic atoms and target motion are explicitly taken into account
