An analytic method is proposed for calculating the asymptotic splittin
g of the lowest energy levels of the Schrodinger operator with a symme
tric double-well potential. The potential describing a chain of pairwi
se interacting quantum particles in a common double-well potential is
considered as an example. The limit of a large number of particles is
investigated.
