*su*(1; 1) Lie algebra and interacting with a two-level atom. We obtain the numerical solution of the associated differential equations and discuss in detail some statistical aspects, atomic population inversion, squeezing phenomena, and negativity. In addition, we analyze the effect of the decay parameter on the population inversion...

_{2}O) concentration based on quartzenhanced photoacoustic spectroscopy (QEPAS). Here, the wavelength-modulation spectroscopy (WMS) with the second-harmonic detection is utilized. We add two metallic tubes acting as a microresonator (mR) to the quartz tuning fork (QTF) sensor design to improve the sensor signal level. After optimization of...

*γ*-irradiation on accelerating the speed of laser ablation of a polyamide is measured for the first time. A linear increase of intensity with a rate of 0.15 mg/s is observed during laser ablation of the polyamide pre-irradiated with

*γ*-rays at a dose of 3,500 kGy. A

*γ*-radiolysis dose of 10 – 20 kGy causes extreme changes in the molecular-topological parameters and the maximum...
