Description

New analytic forms for the parallel diffusion coefficient with adiabatic focusing are presented. For isotropic pitch-angle diffusion, we derive an exact formula for the parallel diffusion coefficient. Those results are correct for weak and strong focusing. For arbitrary pitch-angle scattering, we derive an approximation which is exact up to second order in the focusing strength. Examples and a comparison with previous results are presented too.
