States and properties of metallic systems at a threshold breakdown of the through holes under power laser action (part 2).Susceptibility

Abstract

Abstract. Threshold breakdown of the through holes by power laser radiation of metallic foils is considered as response of metallic system to laser radiation. Binding experimentally determined response to the absolute temperature scale allows to determine the value of the imaginary part of the generalized susceptibility depending on temperature, the critical temperature of the transition "liquid metal -gas", states of the electronic subsystems at this temperature, and the reflectance coefficient values.Key words: Response, imaginary part of the generalized susceptibility, plasm frequency, frequency of electron-ion interaction, critical temperature of second order "liquid metal-gas" phase transition, reflectance coefficient.
