Abstract

Spectroscopic data on alkali-atom dimers residing on the surface of liquid helium nanodroplets have revealed that they are detected primarily in the weakly bound, metastable, spin-triplet state. Here, by measuring the magnetic Stern–Gerlach deflection of a sodium-doped nanodroplet beam, we transparently demonstrate the abundance of high-magnetic-moment dimers. Their electron spins thermalize with the cryogenic superfluid droplets and become fully oriented by the external magnetic field.

氦纳米液滴形成的高自旋钠二聚体的磁偏转

液氦纳米液滴表面碱原子二聚体的光谱数据表明，它们主要处于弱束缚、亚稳态、自旋三重态。在这里，通过测量钠掺杂纳米液滴光束的磁施特恩-格拉赫偏转，我们透明地证明了高磁矩二聚体的丰度。它们的电子自旋与低温超流体液滴一起热化，并在外部磁场的作用下完全定向。

期刊介绍： The Journal of Physical Chemistry (JPC) Letters is devoted to reporting new and original experimental and theoretical basic research of interest to physical chemists, biophysical chemists, chemical physicists, physicists, material scientists, and engineers. An important criterion for acceptance is that the paper reports a significant scientific advance and/or physical insight such that rapid publication is essential. Two issues of JPC Letters are published each month.
