Abstract：
The cross sections and energy spectra of the Coulomb disintegration of （e⁺e^-） and（μ⁺μ^-）at high energies are calculated by using the perturbation expansion of com-posite field theory [1] and the approximate covariant solution to Bethe-salpeter equa-tion with Coulomb potential and spin 1/2, -1/2^[2] . The cross sections of disintegrationof （e⁺t^-） are about 20% less than the cross sections calculated by others [3]. Be-sides; the results obtained in this paper indicate that the cross sections of coulomb di-sintegration of （e⁺e^-） or （μ⁺μ^-） at high energies in singlet state and triplet stateare equal exactly, while in [3] this oicurs only when n=2, and when n=1 the dif-ferenles betwees the rross sections in the two states are about 25%. It is very likelythat there were some mistakes in these calculutions.
