We show that the properties of the heavy-electron superconducting stat
e induced by the interorbital kinetic exchange scale with the effectiv
e-mass renormalization m/m(o) similar to 1/T-K. Explicitly, the pairi
ng potential (J) over tilde similar to J(m(o)/m)1n(2)(m(o)/m*), where
J is the magnitude of the bare Kondo coupling; the coherence length x
i similar to T-K/T( )c, where T-c is the transition temperature, where
as the penetration depth lambda similar to (m/m(o))(1/2) so that lamb
da/xi >> 1. We also determine the scaling of magnetic critical fields.
