Particle-production processes in the Coulomb field of nuclei at high energi
es have been considered, and the electromagnetic properties of hadrons (mes
ons and hyperons) have been investigated in these processes. The results of
previous investigations have been summarized, and new data from the SELEX
(Fermilab) and SPHINX (Institute for High Energy Physics, Protvino) facilit
ies have been discussed. (C) 2000 MAIK "Nauka/Interperiodica".
