Asymptotic approximations to the Mie efficiency factors for extinction, absorption, and radiation pressure, derived from complex-angular-momentum theory and averaged over (=sizeparameter), are given and compared with the exact results. For complex refractive indices N=n+ik with 1. 1<~n<~2. 5 and 0<~k<~1, the relative errors decrease from (1-10) % to (10^-2-10^-3) % between =10 and =1000, and computing time is reduced by a factor of order, so that the Mie formulae can advantageously be replaced by the asymptotic ones in most applications.
