On the theory of nuclear spin relaxation in hydrogen gas Needler, George

Abstract

The generally accepted, though approximate, theory of the relaxation time T₁ of the nuclear spin system in ortho H₂ at low temperatures was developed by Schwinger (see Bloembergen (1948)). In this thesis Schwinger's theory is generalized to the case of arbitrary temperatures. An expression for T₁ is obtained which reduces to the Schwinger formula at low temperatures and ordinary pressures and to a slightly modified Schwinger formula at low temperatures and low pressures. The method used here to calculate T₁ is somewhat different from the method used by Schwinger.
