摘要：

The de Haas - van Alphen measurements of the deuterated molecular conductor (DMeDCNQI)2Cu have been carried out to investigate the Fermi surface and the possibility of the mass enhancement of the conduction electrons near the insulating phase. The Fermi surfaces and the cyclotron masses of the deuterated samples which show the drastic metal - insulator - metal transition are found to be the same as those of the undeuterated sample. The fact shows that the additional mass enhancement due to many body effects is absent near the insulating phase.
