NUCLEAR RESONANCE IN LIQUID AND SOLID HE3 AT LOW TEMPERATURES

Abstract

The cryogenic requirements for the preliminary investigation were comparatively simple and consisted of a chamber containing liquid He-4 which can be cooled to 1K and in which the He-3 cavity is situated. Pressures can be raised to over 150 atm by means of a thermal compression unit. Several different electronic systems were investigated for making nuclear resonance measurements. Measurements of the spin-lattice relaxation time gave values around 1 minute; the true relaxation is known to be closer to 5 min. The short times observed are probably due to impurity or wall relaxation.
