摘要：

The nature of the superconducting state in quasi-one-dimensional organic conductors has remained controversial since its discovery. Here we present results of Se-77 NMR Knight shift (K-s) experiments in (TMTSF)(2)PF6 under 7 kbar of pressure with a magnetic field aligned along the most conducting a axis. We find no noticeable shift in K-s upon cooling through the superconducting transition. Since K-s directly probes the spin susceptibility chi(s), the fact that chi(s) remains unchanged through the superconducting transition strongly suggests spin-triplet superconductivity.
