摘要：

We report the two-dimensional angular-correlation-of-annihilation-radiation measurement of the e + e - (pair) momentum distribution in the organic superconductor kappa-(BEDT-TTF)2Cu(NCS)2. Our data, when compared with tight-binding (Huckel) electronic-band calculations, show features consistent with predicted Fermi surfaces. The structure around Z in our spectrum supports the results from earlier de Haas-van Alphen and Shubnikov-de Haas measurements. In addition, our data show features consistent with the predicted open Fermi surface that runs nearly parallel to YM.
