类似于光学圆二色性,可能具有电子圆二色性,即纵向极化电子通过手性介质的优先传输。使用立体异构体的樟脑蒸汽作为散射目标,我们期待在入射电子能量为1,3,5,7,或10 eV的这种效果。在我们的检测限(-0.02%)内,我们没有观察到自旋相关的非对称传输。斯特克尔科伊索姆克雷斯电子伏服装检测精度(-0.02%)
: Analogous to optical circular dichroism, it is possible to have electron circular dichroism, the preferential transmission of longitudinally polarized electrons through a chiral medium. Using stereoisomers of camphor vapor as a scattering target, we looked for this effect at incident electron energies of 1, 3, 5, 7, or 10 eV. Within our detection limit (-0.02%) we have not obsewed a spin-dependent asymmetric transmission. stkrkoisomkres eV. la pricision nos appareils de ditection (-0.02%) obsewk
