Abstract:
The Coulomb deexcitation of muonic hydrogen in collisions with hydrogen atom has been studied in the framework of the fully quantum-mechanical close-coupling method for the first time. The calculations of the $l$-averaged cross sections of the Coulomb deexcitation are performed for $(\mu p)_n$ and $(\mu d)_n$ atoms in the initial states with the principal quantum number $n=3 \div 9$ and at the relative energies $E=0.1 \div 100$ eV. The obtained results for the $n$ and $E$ dependences of the Coulomb deexcitation cross sections drastically differ from the semiclassical results. Important contribution of the transitions with $\Delta n > 1$ to the total Coulomb deexcitation cross sections (up to $\sim 37\%$) is predicted.
