WebApr 10, 2024 · A new electron-scattering experiment challenges our understanding of the first excited state of the helium nucleus. Figure 1: Inelastic electron scattering off helium nuclei can provide information about the first excited state of helium, which is called 0 2 +. New experiments confirm a discrepancy with theoretical predictions. WebIn quantum mechanics, a singlet state usually refers to a system in which all electrons are paired. The term 'singlet' originally meant a linked set of particles whose net angular momentum is zero, that is, whose overall spin quantum number =.As a result, there is only one spectral line of a singlet state. In contrast, a doublet state contains one unpaired …
