| Research Abstract |
1. Determination of the spatial distributions for produced excited particles
The spatial distributions for produced excited particles are determined using a Monte Carlo Simulation method. The calculations are expanded to the region, which include non-equilibrium condition of electron energies. The behavior of electron swarms in Ne/Ar mixture, Ne, Ar and N_2 are investigated.
2. Loss process of excited particle
The loss process of excited particle have studied by means of the analytical method, which solves the diffusion equation under the third kind boundary condition for N_2(A^3*^+_u). From the result of this analysis, we confirmed the reflection phenomena of excited particles at the boundaries.
3. Determination for fundamental constant of N_2(A^3SIGMA^+_)
The diffusion coefficient, the collisional quenching rate coefficient and reflection coefficient of N_2(A^3SIGMA^+_) are determined from the experiment in the Townsend discharge region. This project is now continued.
4. Report of the investigation result
We have reported three papers and contributed papers, respectivity. One of them is discussed about the loss process of metastable nitrogen molecule N_2(A^3SIGMA^+_). Two contributed papers were presented to ICPIG (1989 and-1991). One has contributed to GD92 (International conference on gas discharges and their applications). Further, two papers are reported to Trans. IEE of Japan.
