D和T核的极化应增加DT分子在HIIF过程中的反应性。在IPN奥赛，我们已经开发了静态极化的高清样品使用“蛮力”（BF）。已经证明，即使在1.5K和1T下，老化技术或双蒸馏也允许获得大于1h的核弛豫时间。有人主张，这是可能的，通过RF的质子和氘的HD分子中包含的常规动态核极化（DNP），使用HD样品蒸馏在奥赛和适当的照射。已经证明了辐照后由双重蒸馏产生的长核弛豫时间的持久性。如果可行的话，HD的DNP将为HIDDT打开可能性，HIDDT具有与HD相同的磁性结构，是HIIF的理想燃料。
The polarization of D and T nuclei should increase the reactivity of DT molecules in HIIF processes. At IPN Orsay, we have developed the static polarization of HD samples using “brute force” (BF). It has been demonstrated, that the ageing technique or the double distillation allow to get nuclear relaxation times larger than 1h, even at 1.5K and 1T. It is advocated that it is possible to achieve by RF the conventional Dynamic Nuclear Polarization (DNP) of the proton and the deuteron contained in the HD molecule, using HD samples distilled at Orsay and suitably irradiated. The persistence after irradiation of the long nuclear relaxation times resulting from the double distillation has already been demonstrated. If feasible, the DNP of HD would open the possibility to polarize DT, which has the same magnetic structure as HD and is the ideal fuel for HIIF.
