Abstract

Based on the ﬁrst-order perturbation theory, we show that the wave function of a photoelectron is a wave packet with the same width as the incident light pulse. Photoelectron detection measurements revealed that the widths of signal pulses were much shorter than the light pulse and independent of the origin (photoemission or other noises), which is an experimental observation of the wave function collapse. Signal pulses of photoelectrons were distributed along the time axis within the same width as the light pulse, consistent with the interpretation of a wave function as a probability distribution.

光电子的波函数及其在光电发射过程中的坍缩

基于一阶微扰理论，我们证明了光电子的波函数是与入射光脉冲宽度相同的波包。光电子探测测量表明，信号脉冲的宽度比光脉冲短得多，并且与源(光电或其他噪声)无关，这是波函数坍缩的实验观察。光电子的信号脉冲沿时间轴分布在与光脉冲相同的宽度内，符合波函数作为概率分布的解释。
