Neutrino oscillations in the field of a linearly polarized electromagneticwave

Neutrino oscillations nu (iL) reversible arrow V-jR in the field of a linea rly polarized electromagnetic wave are studied on the basis of a recently p roposed effective Hamiltonian that describes the evolution of a spin in an arbitrary electromagnetic field. The condition of resonance amplification o f the oscillations is analyzed in detail. A method is developed for qualita tively studying solutions to the equation of neutrino evolution in the reso nance region. This method can be used to explore neutrino oscillations in f ields of various configurations. (C) 2001 MAIK "Nauka/Interperiodica".
