Abstract
We study properties of atoms, in which substitute fermions–electrons by bosons, namely \( \pi^{ - } \)-mesons. We perform calculations in the frame of modified Hartree-Fock (HF) equation. The modification takes into account symmetry of the pair of identical bosons wave function, doubling instead of eliminating self-action as in the Fermion case. As examples of simple process with pion atoms, we consider their photoionization and collisions with other pions.

Notes
- 1.
We employ the system of units that defines \( m = e = \hbar = 1 \). Here m is the mass, in electron case \( m = m_{e} \), in pion case \( m = m_{\pi } \); \( m_{\pi } /m_{e} \approx 273.13 \).
