Low-field method for measuring proton gyromagnetic ratio

Abstract

A measurement of the proton gyromagnetic ratio in water by the low-field method is in progress. The Earth's magnetic field is compensated down to 1 nT at the center of Helmholtz coils in the constructed nonmagnetic facilities. The solenoid former of fused silica has been fabricated by the screw grinding and lapping within the dimensional variations of a few micrometers.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
