The interlayer magnetoresistance ρzz of the organic metal \cuscn is studied in fields of up to 45 T and at temperatures T from 0.5 K to 30 K. The peak in ρzz seen in in-plane fields, a definitive signature of interlayer coherence, remains to Ts exceeding the Anderson criterion for incoherent transport by a factor ∼30. Angle-dependent magnetoresistance oscillations are modeled using an approach based on field-induced quasiparticle paths on a 3D Fermi surface, to yield the T dependence of the scattering rate τ−1. The results suggest that τ−1 does not vary strongly over the Fermi surface, and that it has a T2 dependence due to electron-electron scattering.
