| Outline of Final Research Achievements |
The presence of precursor electrons ahead of a shock wave was confirmed by the triple-probe measurement. The generation mechanism of precursor electrons is found to be the photoionization reaction from the comparison with a theoretical analysis. In addition, spectroscopic measurements were conducted to measure the radiation behind a shock wave and the electron density distribution was obtained by evaluating the stark broadening of hydrogen Barmer line. As a result, it is found that the radiative energy loss occurs in the region behind the shock wave.
