Abstract:
New correction for charged particles interaction in gasios plasma was proposed and validated.
Using this correction in Saha equations allowed to formally apply them to zero temperature. This
gives reasonable values for ionizatoin degree and thermodynamics. This essentially expands Saha
equations to extra-high densities and moderate temperatures, where plasma becomes liquid.
Addional classic Debay model was improved and the Simple harmonic oscillators model was
disproven.
Liquid plasme is well described with the Thomas–Fermi model with quantum and excange
corrections. A superfast algorithm was proposed to solve equations of this model. By means of
special interpolation Thomas–Fermi model is joined with the Saha model. This gives wide-range
queation of state for gasion and liquid plasma.
Accrording to this model hugoniots were calculated with radiation terms. Shell effects were
analyzed.
