• In a linear z-pinch discharge of helium, the continuum emission at the maximum contraction of the plasma and some forbidden lines during the succeeding period of a few μsec were observed at the initial gas pressure of 6.0 Torr. At the maximum contraction the plasma was found to be a black body in the direction through the axis of the discharge tube and a gray body in the direction perpendicular to the axis. From the intensity of continuum and optical thickness the temperature and the electron density have been determined to be (1.5±0.2)×10^4°K and 5∼7×10^<18>cm^<-3>, respectively. The intensity ratios of the forbidden lines to the allowed ones as well as their shifts were measured in n^3L2^3P series. From these results it has been proved that the electron density of the plasma changes from 1 to 0.1×10^<18> cm^<-3> in a few μsec after the maximum contraction.
