摘要
自旋极化电子束的获得,为自旋极化电子与原子碰撞符合实验研究奠定了基础,通过符合实验,已经能够获得电子原子碰撞的更多的信息,而且能够探测到碰撞过程中的自旋相关效应,并为分子结构及固体表面的研究提供了一种新的研究手段。
An ensemble of electron is said bo be polarized if the electron spins have a preferential orientation so that there exists a direction for which the two possible spin states are not equally polulated. The more information of atoms and the corresponding spin effects were measured through the spin polarized electron-photon coincidence experiments. The further applications of spin polarized electron beams will be in the fields of chiral molecules and magnetism surface.
