• Resumen

  • In the present work, we have calculated the radiative transfer, it means the radiative energy that escapes from a plasma formed from a mixture of Argon−Helium. The computations take into account several pressures between 1 ≤ p ≤ 100 atm in the temperatura T wide range of 5000 − 30 000 K. In the case of the plasmas is supposed to be in local thermodynamic equilibrium. Where the contributions have been treated separately in the calculation: atomic emission lines self-absorbed and not self-absorbed, continuum (radiative attachment, radiative recombination and radius). The results show that a large part of radiation is absorbed at the first crossed millimeter and also the contribution of resonance lines is very important. These are the lines which are strongly absorbed.
