Two measurable characteristics of microwave one-mode photon states are discussed: a rotated quadrature distribution (tomogram) and normally/antinormally ordered moments of photon creation and annihilation operators. Extraction of these…
Radionuclides with half-lives ranging from some years to billions of years presumably synthesized outside of the solar system are now recorded in `live' or `fossil' form in various types of materials, like meteorites or the galactic cosmic…
A survey of atomic binding energies used by general purpose Monte Carlo systems is reported. Various compilations of these parameters have been evaluated; their accuracy is estimated with respect to experimental data. Their effects on…
