Conditions for observing IR chemiluminescence and the role of condensation in metal oxidation reactions
… was greater 1010 3 than ~ cm-sec-I, then only ""black body"" radiation could be seen from the reaction. Most of the studies were on the Li/I2 system which is unique in that the phase diagrams of Li and LiI in the P-T ranges of interest are almost identical. This property permitted a relatively …

Theory of the lunar photoelectron atmosphere
… the illumination of the lunar surface by solar (black body) radiation and also the distribution in energy of the electrons ejected for each photon energy. An adiabatic gas model of the photoelectron atmosphere provides an independent check of the results.</p> <p>Assuming a metalic [sic] surface …

Charge dynamics in superconducting double dots
… for the pair breaking we attribute it to black-body radiation in the cryogenic environment. We also drive the breaking process with a continuous microwave signal, and find that the rate is linearly proportional to incident power. This suggests that a single photon process is responsible, …

Radial-zoned thermal accretion disk model around black holes
… the theory of accretion disks around black holes. Accretion disk models are applied to the dynamics of compact objects surrounded by material with organized angular momentum. The disk forms due to the process by which differentially rotating fluid layers interact with each other and …

Solar thermoelectrics for small scale power generation
… tool (Z-meter) has been developed with proper radiation suppression (20x below black body radiation) and low system parasitics (41.6% lower electrical contact parasitic that previous published results). We investigated novel metalsemiconductor superlattice structures ((HfZr)N/ScN) using the …

Quantum Nuclear Dynamics: Application to Spin-Forbidden Transitions and Lifetime of Vibrational States
… and absorption and emission stimulated by the black body radiation. We demonstrate that the ground vibrational states of the diatomic alkali molecules have much longer lifetimes than the excited states. In contrast, the lifetimes of the highly excited vibrational states of the …

Numerical Modelling of LOX Droplet Combustion in Hydrogen under Micro-gravity Conditions
… single numerical solution of droplet combustion. Radiation heat transfer is also considered, as an addition to the flame model to match the rate of heat transfer for droplet evaporation obtained in experimentation. The new EBI-DNS solver predicts flame temperatures close to 3100 K, which is quite …

The binary system containing the pulsar PSR 1913+16 and ultra-violet and x-radiation from accreting magnetic white dwarfs
… precession require that the companion be a black hole, a neutron star, a white dwarf or a helium main-sequence star. Observable second-order relativistic effects mayor may not further restrict the list of candidates. The discussion summarjzes Masters and Roberts, 1975 Ap. J. (Letters), …

Semi-Empirical Lifetimes for High-Energy Rydberg States of ¹³³Cs Neutral Cesium in a Blackbody Radiation Field
… out at higher temperatures which allow thermal radiation to significantly deplete the lifetime of states with principal quantum number greater than. n≈16 Therefore we have also explicitly included blackbody-induced transitions in our calculations, in order to evaluate the lifetimes at …
