9402655 Jean This proposal provides funds to purchase a positron source and pursue exploratory studies of a class of organic superconductor. The materials are bis(ethylenedithio)tetrathiafulvalene complexes, as well as the new fullerene C-60 materials. The project involves both experiment methods to determine the angular distribution of positron annihilation in that materials, and quantum chemical calculations to provide an interpretation of these data in terms of the Fermi surface in these materials. The results are of fundamental interest but may also be of technical importance as they provide information about the superconducting state in these materials. ***

小行星9402655 该提案提供资金购买正电子源，并对一类有机超导体进行探索性研究。 这些材料是双（亚乙基二硫代）四硫富瓦烯配合物，以及新的富勒烯C-60材料。 该项目涉及确定材料中正电子湮灭角分布的实验方法，以及根据这些材料中的费米面对这些数据进行解释的量子化学计算。 这些结果具有根本意义，但也可能具有技术重要性，因为它们提供了有关这些材料中超导态的信息。 ***
