摘要

本文对迄今为止明确利用中子的自旋-12粒子性质所进行的所有中子干涉实验作了简要的综述。它涵盖了自旋子的4π周期的验证,核相移和自旋旋转对中子波函数的协同作用,费米子自旋态叠加的量子力学原理的演示以及最近的双共振实验,其中两个干涉光束通过空间分离的振荡磁场传播。最后,还将提出一个关于所谓的“后期选择”的极化中子实验的建议。

Polarized neutron interferometry: A survey

A brief summarizing review is given of all those neutron interferometric experiments performed hitherto which explicitly use the spin-12 particle properties of the neutron. It covers topics as the verification of the 4π-periodicity of spinors, the cooperative action of nuclear phase shift and spin-rotation on the neutron wave function, the demonstration of the quantum mechanical principles of fermion spin-state superposition and the more recent double resonance experiments where the two interfering beams propagate through spatially separated oscillatory magnetic fields. Finally a proposal will be presented also for a so-called “late-choice” experiment with polarized neutrons.
