WebThe Doppler linewidth of the 5d[32] 1 0 -6p[32] 1 transition of xenon (Racah notation) at 2.026 μ in a helium-xenon discharge has been measured directly. Earlier, this transition has been shown to exhibit large optical amplification. The Doppler linewidth determination has been accomplished by measuring the optical gain in a helium-xenon discharge tube as a … Weba The neon, argon, krypton, and xenon transitions are listed in both Paschen and Racah notation for convenience. Pertinent maser data are given for some of the strongest transitions, and these data (except for cesium) refer to a confocal system having an …

In atomic physics, a term symbol is an abbreviated description of the total spin and orbital angular momentum quantum numbers of the electrons in a multi-electron atom. So while the word symbol suggests otherwise, is represents an actual value of a physical quantity. For a given electron configuration of an atom, … See more The usual atomic term symbols assume LS coupling (also known as Russell–Saunders coupling), in which the atom's total spin quantum number S and the total orbital angular momentum quantum number L are " See more It is relatively easy to calculate the term symbol for the ground state of an atom using Hund's rules. It corresponds with a state with maximum S and L. 1. Start with the most stable electron configuration. Full shells and subshells do not contribute to the … See more Basic concepts for all coupling schemes: • $${\displaystyle {\boldsymbol {\ell }}}$$: individual orbital angular momentum vector for an electron, See more • Quantum number • Angular quantum numbers • Angular momentum coupling • Molecular term symbol • Hole formalism See more For a given electron configuration, • The combination of an $${\displaystyle S}$$ value and an $${\displaystyle L}$$ value is called a term, and has a statistical weight (i.e., number of possible states) equal to $${\displaystyle (2S+1)(2L+1)}$$; • A combination of See more The process to calculate all possible term symbols for a given electron configuration is somewhat longer. • First, the total number of possible states N is calculated for a … See more These are notations for describing states of singly excited atoms, especially noble gas atoms.
