WebA change to the energy of an electron within an atom, or more rarely within a molecule, in which the electron remains attached (bound) to the atom or molecule both before and … WebThe plasma photoabsorption coefficient is calculated in the ultraviolet region (4·0–25·0 eV). The most pronounced effect is due to the bound-free absorption of cesium at energies below the hydrogen ionization energy. This effect is important at low plasma temperatures.

WebShow that Paschen bound- free absorption (corresponding to ionization from the n 3 level of hydrogen) occurs primarily in the visible spectrum where the solar light output peaks and therefore is expected to dominate the contribution of neutral hydrogen to continuum absorption at visible wavelengths.

WebOct 23, 2024 · Kramers' opacity law describes the opacity of a medium in terms of the ambient density and temperature, assuming that the opacity is dominated by bound-free absorption (the absorption of light during ionization of a bound electron) or free-free absorption (the absorption of light when scattering a free ion, also called …
WebThe gaunt factors for bound-free absorption in a pure Coulomb field are computed for bound states through the l5th shell and for free electron energies 9/ Z/sub 2/ from 2.5 x 10/sup -3/to 4 x lO/sup 4./ Rydbergs. The results are presented in tables and graphs and include also the gaunt factors averaged over a complete shell.
