Quantum Monte Carlo study of the Ne atom and the Ne+ ion
Quantum Monte Carlo study of the Ne atom and the Ne+ ion

... The “exact” nonrelativistic (NR) infinite-nuclear-mass energies are taken from Ref. [3]. All the DMC energies quoted in Table 1 have been extrapolated to zero time step. We used a range of small time steps and performed linear extrapolations of the energies to zero time step. Optimizing the orbitals ...

... For ideal plane wave (100% coherent),  (phase) is constant, independent of r (position) and t (time). But in reality, = (r, t) At any z-value z0, if the phase difference between subbeam A and A’ is small, namely (A’)-(A)<<2, we can then consider  as constant, and the two beam can interfere ...

X-ray fluorescence



X-ray fluorescence (XRF) is the emission of characteristic ""secondary"" (or fluorescent) X-rays from a material that has been excited by bombarding with high-energy X-rays or gamma rays. The phenomenon is widely used for elemental analysis and chemical analysis, particularly in the investigation of metals, glass, ceramics and building materials, and for research in geochemistry, forensic science and archaeology.
