对于通过双蒸馏纯化的 HD 样品，HD 样品的静态极化是通过“强力”实现的。质子偏振超过60%，氘子矢量偏振超过14%。事实证明，老化技术可以使 1.5 K 和 1 T 的弛豫时间超过一周。主张HD的常规动态极化对于HD分子中所含的质子和氘核应该是可行的。这将大大简化目前用静态方法极化的高清目标进行核物理实验所需的机械。
The static polarization of HD samples has been achieved using “brute force”, for HD samples purified by double distillation. Proton polarization in excess of 60% and deuteron vector polarization higher than 14% have been reached. It has been demonstrated that the ageing technique allows to get relaxation times at 1.5 K and 1 T larger than a week. It is advocated that the conventional dynamic polarization of HD should be feasible for the proton and the deuteron contained in the HD molecule. This would simplify considerably the machinery presently necessary to perform nuclear physics experiments with HD targets polarized by the static method.
