The high-order relativistic corrections to the Zeeman g-factors of the helium atom are calculated. AII the relativistic correction terms and the term describing
A more general expression for the quark propagator including both chiral and diquark condensates has been derived by using energy projectors. This makes it poss
A new-style discharge tube for a metal vapour laser has been designed and built. SrBr2 was successfullyused to replace the metal strontium as a working medium.
Three-jet events in e+ e- collisions at 91.2 GeV are investigated using both HERWIG and JETSET Monte Carlo generators. The angles among the three jets are used
By comparing of the spectra from the Chandra LETGs observation with the synthetic spectra of argon, we identify two weak emission lines, that is, the Ar XV 27.4
Using a simple two-parameter wavefunction, we calculate variationally the binding energy of positively and negatively charged excitons in GaAs/AlxGa1-xAs quantu
