Query: Test for interlayer coherence in a quasi-two-dimensional superconductor   Peaks in the magnetoresistivity of the layered superconductor
$\kappa$-(BEDT-TTF)$_2$Cu(NCS)$_2$, measured in fields $\leq 45$ T applied
within the layers, show that the Fermi surface is extended in the interlayer
direction and enable the interlayer transfer integral ($t_{\perp} \approx 0.04$
meV) to be deduced. However, the quasiparticle scattering rate $\tau^{-1}$ is
such that $\hbar/\tau \sim 6t_{\perp}$, implying that
$\kappa$-(BEDT-TTF)$_2$Cu(NCS)$_2$ meets the criterion used to identify
interlayer incoherence. The applicability of this criterion to anisotropic
materials is thus shown to be questionable.
