摘要: La mesure du rayonnement fond continu d'un plasma permet de determiner la densite electronique sans faire d'hypothese sur l'etat d'equilibre thermodynamique milieu, a condition connaitre les facteurs correctifs Biberman correspondant aux differents continuum recombinaison. En particulier, dans un d'argon haute temperature (Te>18 000 K), contribution l'emission continue recombinaison des atomes deux fois ionise (Ar III) doit etre prise en compte. Malheureusement, il n'existe litterature que tres peu donnees relatives au facteur Ar III pour ions III. Mettant profit le diagnostic precis zone cathodique arc electrique fonctionnant l'argon, nous avons premiere ce = 468,8 nm une Te~25 K. Continuous background intensity measurement is very convenient method to determine the free electron density because it does not require local thermodynamic equilibrium state in plasma. For high-temperature argon arcs difficulty occurs there are few data permitting inclusion of into radiation. Using reliable results from our experiments, we report Biberman's factor, which necessary use radiation at 468.8 as tool temperatures Te around 25
