Abstract
Experiments were performed to investigate the behavior of lead near it s critical point. Emission spectra of shocked lead samples during unlo ading into helium at different initial pressures were measured by an o ptical multichannel analyzer (OMA), as well as by a fast optical pyrom eter. To describe the obtained experimental data, a model of a thin mi xture layer was suggested, in which helium emits due to the presence o f external electrons from lead.
