متن کاملKoopmans' springs to life.
The meaning of orbital energies (OOEs) in Kohn-Sham (KS) density functional theory (DFT) is subject to a longstanding controversy. In local, semilocal, and hybrid density functionals (DFs) a Koopmans' approach, where OOEs approximate negative ionization potentials (IPs), is unreliable. We discuss a methodology based on the Baer-Neuhauser-Livshits range-separated hybrid DFs for which Koopmans' a...

متن کاملRadioactivity Concentration in Sediment and Water Samples of Hot Springs of Mahallat and Soil Samples of Their Neighboring Environs
The activity concentrations of 226Ra, 232Th, 40K and 137Cs in water and sediment samples from hot springs of Mahallat and soil samples from their neighboring environs have been determined using two high resolution high purity germanium (HPGe) detectors with relative efficiencies 38.5% and 55%. The activity concentrations of 226Ra, 23...
