Nuclear Resonance in Condensed System at Low Temperatures

摘要

A program on experimental study of nuclear resonance in condensed systems was initiated in this laboratory to understand some microscopic features of the atomic movements. Low temperatures are required to investigate a simple element like helium 3, for which the translatory movement is the only one responsible for the relaxation of the nuclear spin system to the thermal bath of the atoms themselves. The apparatus needed to accomplish this investigation was mainly built in this laboratory and consists essentially of the following components.n1)tThe electromagnetn2)tThe electronicsn3)tThe gas manifold systemnThe cryostat
