Combinational processes in dense high-temperature plasmas
  The dependence of the real and imaginary parts of the refractive index on the dielectric capacity was obtained for different values of the nonideality parameter, by the help of an ion-ion psevdopotential of fully ionized dense high-temperature plasma, taking into account local fields, quantum and collective effects.
