Abstract
Some properties of pionium are studied. The decay width in the Is stat
e is related to the scattering lengths. Chances to produce pionium in
hadron-hadron collisions are calculated. Special attention is paid to
the effects of an external Coulomb field on the atomic formation proce
ss. Corrections to the coalescence model are found and the rate of 2p
state production due to the external field is calculated.
