一种推导各向异性自旋交换率的方法

Method for deducing anisotropic spin-exchange rates

T. G. Walker, I. A. Nelson, S. Kadlecek

摘要:

使用测量的从碱原子到He-3的自旋转移速率,结合由于He-3和He-4的碱原子的自旋弛豫速率,应该可以区分各向同性和各向异性的自旋交换。这将给出在自旋交换光泵浦中可达到的He-3偏振的基本限制。对于K-He,我们发现极限为0.90+-0.11。

英文摘要:

Using measured spin-transfer rates from alkali atoms to He-3, combined with spin-relaxation rates of the alkali atoms due to He-3 and He-4, it should be possible to differentiate between isotropic and anisotropic spin-exchange. This would give a fundamental limit on the He-3 polarization attainable in spin-exchange optical pumping. For K-He, we find the limit to be 0.90+-0.11.
