The infrared absorption spectra of Sm3+ ions in CaF2 crystals are measured between 15 and 300 K. The temperature independence or dependence of the absorption bands, which are due to electric-dipole forbidden 4f5 4f5 transitions, is interpreted in terms of static or dynamic electron-lattice ...
Combining Tauc plot, density functional theory (DFT) calculations, and in situ FTIR spectrum, we propose a photocatalytic mechanism of the activated parity-forbidden electron transfer of d-d orbitals under IR light irradiation (Fig. 1c). As a result, the ultrathin CSON exhibit effective ...
Parity- and time-odd atomic multipoles in magnetoelectric GaFeO3 as seen via soft x-ray Bragg diffraction We present resonant soft x-ray Bragg diffraction data on the space-group forbidden (010) reflection at the FeLedges of magnetoelectric GaFeO. Observed inte... U Staub,Y Bodenthin,C Pia...
Calculation of the parity-forbidden decay width of 6Li*(Jpi =0+, T=1; E*=3.56 MeV)→α+d The decay of 6Li*(0+, 1; 3.56 MeV) to alpha +d occurs due to the admixture of continuous-spectrum 0- states with the 0+ state considered. To calculate the width, Gamma , of this ...

Electric dipole (E1) transitions, which normally dominate atomic spectroscopy, are forbidden between states of like parity. However, H PNC mixes s and p states and causes, in some cases, small E1 transition amplitude to appear and to interfere with transitions (M1, E2) normally present but ...
