Mass of a photoelectron
WebPhotoionization is the process in which molecule (M) is ionized by a beam of photons, in which the molecule will lose an electron: (2) M + h ν → M + ( E i n t) + e This process of photoionization follows the three-step model. The three-step model breaks down the process of photoionization into three independent steps: WebWe can also use this equation to find the photoelectron velocity \text v v, which is related to \text {KE}_\text {electron} KEelectron as follows: \text {KE}_\text {electron}=h\nu …
