heal.abstract	Momentum decoupling arises when small momentum transfer processes dominatethe electron-phonon scattering and implies that anisotropies insuperconductivity are driven by the anisotropies of the density of states.Considering an isotropic s-wave interaction in the momentum decoupling regimewe give a natural simultaneous explanation to various aspects of ARPES andtunnel experiments on $Bi_2Sr_2CaCu_2O_8$, including the correlation of gapmagnitude	en
