Tensor polarization in a deuterium target of non‐uniform spin temperatures

Calculations are described which allow for the measurement of the tensor polarization of a polarized deuterium target which has a distribution of spins. The tensor polarization can be determined uniquely providing a careful measurement of the vector polarization is made by the TE method and an accurate determination is made of the asymmetry of the NMR spectrum. The correct value for the average tensor polarization is between the value obtained from the TE method and that obtained from the asymmetry method.
