ABSTRACT:
This paper presents new experimental
results concerning the PeTa effect—infrared characteristic radiation under first
order phase transitions, especially during deposition and condensation of vapours/gases
and the crystallisation of melts. The abbreviation “PeTa
effect” means Perel’man-Tatartchenko’s effect. The nature of the PeTa effect is transient radiation that a particle (i.e.,
atom, molecule or/and cluster) emits during a transition from a meta-stable higher
energetic level (in a super-cooled melt or super-saturated vapour) to the stable
condensed lower level (in a crystal or liquid). The radiation removes latent heat
with photons of characteristic frequencies that are generated under this transition.
This paper is the second in a set describing the appearance of PeTa radiation under
air cooling with deposition and condensation of air components. The radiation was
recorded using an IR Fourier Spectrometer with a highly sensitive MCT detector.
Certain peculiarities of the recorded radiation as well as its applications in the
physics of the atmospheres of Earth and Jupiter are analysed.
