Abstract

This talk discusses a new model of optical transmittance of ultra-diluted gas. The model considers individual gas particles' non-locality, the quantum effect of wave function spreading derived from solving the Schrödinger equation for a free particle. I indicate some quantitative and qualitative consequences of this model. One of them is that measured transmittance depends on the detector size. Namely, for small detectors, such a gas's optical transmittance increases significantly, up to 100%, compared to the classical predictions. The mathematical foundation of the model reveals how the transmittance of a closed system may rise to compare to classic models. I show the connection with classical models by deriving the Beer-Lambert law equation within its applicability range. I also show the relationship with some interpretations of quantum mechanics.

I briefly refer to the conducted lab experiment that measures gas transmittance in parallel with a pair of detectors with different diameters. I discuss results that are in agreement with the model.

Dark and thin interstellar and intergalactic regions seem to be natural regions for such a gas to occur. The transmittance model is a part of the radiation transfer equation. Besides, the model predicts the gas density depends on the intensity of the background radiation field. In this regard, the talk concludes by indicating the possible related astrophysical phenomena.
