The Auger decay rates of the 1s(1/2)((e))ns(1/2)((mu)) state in the ex
otic mesic helium atoms is calculated. The smallness of the ratio beta
= m(e)/m(mu) approximate to 1/200 enables us to take into account the
electron-meson interaction in the second-order perturbation theory an
d present the probability of the process in a closed analytic form.
