Webionization, in chemistry and physics, any process by which electrically neutral atoms or molecules are converted to electrically charged atoms or molecules (ions) through gaining or losing electrons. Ionization is one of the principal ways that radiation, such as charged particles and X rays, transfers its energy to matter. In chemistry, ionization often occurs … WebIonizing radiation is used in a wide variety of fields such as medicine, nuclear power, research, and industrial manufacturing, but presents a health hazard if proper …

WebThe photon energies and fluences used in the present experiments produce strong B + signals by 2-photon ionization of gas-phase uracil 1 and thymine, 42 whereas we can only speculate about the possible efficiency of multi-photon ionizing (S–H) neutrals. The calculations of PPT are done in the E-gauge, meaning that the laser field is taken as electromagnetic waves. The ionization rate can also be calculated in A-gauge, which emphasizes the particle nature of light (absorbing multiple photons during ionization). This approach was adopted by Krainov model based on the earlier works of Faisal and Reiss. The resulting rate is given by scranton weather cam
