Abstract:
It is shown, how the measurements of life times of dimesoatoms $A_{2\pi}$ and $A_{\pi K}$ make it possible to check and obtain more precise values for such important parameters of
the quark model of superconductivity type as the mass of $\varepsilon (700)$-meson and the coefficients
of the $q^2$-expansions of quark loops (i.e. formfactors of vertices of phenomenological
chiral lagrangians). The life times of dimesoatoms $A_{2\pi}$ and $A_{\pi K}$ as well as
scattering lengths of $\pi\pi$ and
$\pi K$-systems are found.
