We present high accuracy relativistic coupled cluster calculations of the first and second ionisation potentials electron affinity heaviest element in Periodic Table, Og. The results were extrapolated to basis set limit augmented with higher order excitations (up perturbative quadruples), Breit contribution, QED self energy vacuum polarisation corrections. have performed an extensive investigat...

Using photoelectron spectroscopy, we interrogate the cyclic furanide anion (C(4)H(3)O(-)) to determine the electron affinity and vibrational structure of the neutral furanyl radical and the term energy of its first excited electronic state. We present the 364-nm photoelectron spectrum of the furanide anion and measure the electron affinity of the X̃(2)A(') ground state of the α-furanyl radical t...

Models and methods to determine the absolute binding energy of 4f -shell electrons in lanthanide dopants will be combined with data on the energy of electron transfer from the valence band to a lanthanide dopant. This work will show that it provides a powerful tool to determine the absolute binding energy of valence band electrons throughout the entire family of insulator and semiconductor comp...
