Cross section of hydrogen
WebThe ionization cross-section measurements for SiH 4 and for the stable Si-organic molecules were carried out in a high-resolution ( m /∆ m = 40,000) double-focusing sector field mass spectrometer (MCH 1310) of E-H configuration with a Nier-type electron impact ion source, as described by Tarnovsky et al. (1994) and Basner et al. (1997a). WebSep 12, 2024 · Figure 8.2.1: A representation of the Bohr model of the hydrogen atom. With the assumption of a fixed proton, we focus on the motion of the electron. In the electric field of the proton, the potential energy of the electron is. U(r) = − ke2 r, where k = 1 / 4πϵ0 and r is the distance between the electron and the proton.
