• The structure of a nonlinear magnetosonic wave in a multiple-ion-species plasma isanalytically investigated, and tl?e elemeuatal composition of ions reflected by tltemagnetosonic wave is studied. Firstly, stationary solutions of magne!tosonic wavespropagating perpendicularly to a magrxctic field in a plasma consisting of electronsand two-species tons are obtained fronx a fluid model. Secondly, on the basis of thesolitary wave soltution, cortditions for ion reflection are discussed. Ther?, the fractionof high-energy ions produced by a magnetosonic wave is expressed in let ms of the ionmass, charge, thermal speed, Alfven speed, and wave amplitude. It rapidly decreaseswith increasing mass. It is found that most of the light ions can be reflected in a multipie-ioua-species )vlasma even for small-amplitude waves if the masses of llte main com-ponent 10115 are sufficiently heavy.composition of accelerated ions, multiple ion species, magnetosonic wave
