transition in Helium, and I have come across a question. It is clear that triplet-singlet transition are not allowed, i.e. ΔS=0. But in my book (Foot's Atomic Physics) it says that Δl = ±1. This is what I don't understand. The selection rule Δl = ±1 we derived for.....
violates this last selection rule, and intercombination transitions, whose probabilities are greater the greater the atomic number of the element, appear. Special selection rules for electronic, vibrational, and rotational molecular spectra exist for molecules, rules that are determined by the symmetry ...

Selection rule effects associated with long-range transition dipole scattering can be significant in electron energy loss spectroscopy (ELS) for loss energies up to 10–12 eV (or higher) on a variety of metal and semiconductor surfaces. These effects will appear in ELS studies of the electronic ...
The electron-phonon (el-ph) and phonon-phonon interactions play crucial roles in determining the electronic and thermal transport properties of materials. Using the group theory and ab-initio calculations, we have derived the full-landscape selection rules for intravalley and intervalley scattering for...

This chapter sets the scene by exploring the motives, methods and magnitudes of gender-biased sex selection (GBSS) drawing from socio-demographic and anthropological research. It starts out by discussing the motives (or reasons) behind GBSS, reviewing ge

We report the spectroscopic observation of a resonant transition that breaks a selection rule in the quantum Rabi model, implemented using an LC resonator and an artificial atom, a superconducting qubit. The eigenstates of the system consist of a superposition of bare qubit-resonator states with a...
