Measurements are carried out of electron densities and temperatures in a plasma produced behind an electromagnetically driven, reflected shock wave in a T-tube filled with hydrogen at an initial pressure of 1.0 Torr. The ranges of the measured electron densities and temperatures are respectively from 10^<17> to 10^<15> cm^<-3> and from 2.5×10^4 to 10^4°K. The electron densities are determined by the 35-GHz microwave reflection technique. These measured values in good agreement with those determined from Stark broadening of the H_β line. The electron temperatures are determined from the ratio of the total spectral line to continuum intensity, and from the measured collision frequency and electron density. The observed plasma decay is interpreted in terms of the collisional-radiative electron-ion recombination theoretically calculated by Bates, Kingston and McWhirter, who take account of the effect of the ionization.
