“…Recording PeTa radiation in this IR range provides support for our window of transparency (WT) model for PeTa radiation in supercooled melts [40]. It allows also the design of a cavity-free pulsed laser on the basis of supercooled melt…”

“…However, the PeTa radiation can be detected from a supercooled melt even if the melt in the normal state is not transparent to the PeTa radiation. In [40], we called this phenomenon the transparency window for the PeTa radiation. Indeed, this system contains both the main energy level (crystal) and the exited one (supercooled melt).…”

The paper presents a physical model of a natural phenomenon, the glow of bubbles at hydrothermal vents formed during underwater volcanic activity. The basis of the model is characteristic non-equilibrium radiation under first order phase transitions that since 2010 has been referred to as the PeTa (Perelman-Tatartchenko) effect. This is the fourth paper in a series developing the model for similar physical phenomena: cavitational luminescence (CL), multi-bubble sonoluminescence (MBSL), single-bubble sonoluminescence (SBSL) and laser-induced bubble luminescence (LIBL). The previous three papers were published during 2017-2018 in this Journal. In the third one we have shown that above mentioned physical effects can be generalized as a phenomenon that we have titled "Vapour bubble luminescence" (VBL). VBL is very clearly represented in a non-equilibrium phase diagram. The essence of VBL is as follows: when there is a local decrease in pressure and/or an increase of temperature in a tiny volume of a liquid occurs, one or several bubbles filled with vapour will appear. Subsequently a very rapid pressure increase and/or temperature decrease in the same volume of liquid leads to supersaturation of the vapour inside the bubble. Upon reaching critical vapor density, instantaneous vapour condensation and emission of the phase transition energy that is accompanied by a flash (this is the PeTa effect) results in a sharp pressure decrease and the bubble collapses due to the pressure drop. This process is accompanied by a shock wave in the liquid. A similar effect occurs if bubbles filled with hot steam, for example from a cappuccino machine, are injected into a relatively large volume of cold water. The VBL model explains all experimental data concerning CL/MBSL/SBSL/LIBL and the relatively new natural phenomenon, the glow of bubbles at hydrothermal vents. Several model experiments demonstrate the PeTa effect under similar conditions. Additionally, we define the PeTa effect in all its manifestations on a non-equilibrium phase diagram. This clarifies which niches can contain VBL processes. We also demonstrate the window of transparency (WT) for

“…The radiation removes latent heat by photons with characteristic frequencies that are generated under this transition. Previous papers present theoretical [1,[5][6][7][8][9] and experimental [2][3][4]7,[10][11][12][13][14][15][16][17][18][19][20][21] evidences of the PeTa effect, but as highlighted in [22], additional investigations concerning atmospheric phenomena are needed. This paper is the second paper of a set.…”

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.

The previous papers [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] present experimental and theoretical evidence for the PeTa effect, but as underscored in the discussion in [5], additional investigations concerning atmospheric phenomena are needed. In this paper, another striking demonstration of the PeTa effect is presented-infrared radiation during the deposition and condensation of air components at the temperature of liquid nitrogen.…”
