Abstract: | Features of the interaction of moving neutral atoms, molecules, and clusters with a superlattice field (for example, the system
of linear magnetic and electric domains) are considered. It is shown that the character of the particle motion depends on
the ratio of the frequency ω21 of the internal electromagnetic resonance to the bounce frequency Ω
s
determined by the superlattice period, the velocity of the particle motion, and the possible moments of the particle in the
ground d
11 and excited d
22 states. The conditions for regimes of attraction and repulsion of particles by the superlattice are considered. The preconditions
for formation of a one-dimensional potential well located far from the superlattice and for stable channeling of neutral and
charged particles in this well are also considered. Depending on the ratio of ω21 to Ω
s
, particle sorting and beam separation occur during interaction of the multicomponent beam consisting of different particles
with the superlattice field. |
