	<span style=\"font-family:Verdana;\" lang=\"EN-GB\">This paper presents new experimental evidence of the PeTa effect</span><span style=\"font-family:Verdana;\" lang=\"EN-US\">¡ªinfrared </span><span lang=\"EN-GB\"><span style=\"font-family:Verdana;\">characteristic radiation under first order phase transitions, especially the crystallization of melts and the deposition and condensation of vapours/gases. The PeTa effect describes the transient radiation that a particle (</span><i><span style=\"font-family:Verdana;\">i.e</span></i><span style=\"font-family:Verdana;\">., atom, molecule or/and cluster) emits transient radiation</span></span><span lang=\"EN-GB\"> </span><span lang=\"EN-GB\"><span style=\"font-family:Verdana;\">dur</span><span style=\"font-family:Verdana;letter-spacing:-0.1pt;\">ing a transition from a meta-stable higher energetic level (in a super-cooled melt or a super-saturated vapour) to the stable </span><span style=\"font-family:Verdana;\">condensed lower level (in a crystal or a liquid). The radiation removes latent heat with photons of characteristic frequencies that are generated under this transition.
