摘要：

Superconductivity was observed in a second quasi-one-dimensional organic conductor (TMTSF)//2AsF//6, at a temperature of 1. 1 K under 12 kbar. The establishment of the superconducting state is apparently not related to the existence of a soft external phonon mode at 2 k//F, since under atmospheric pressure X-ray diffuse scattering fails to detect any Kohn anomaly at low temperature.
