The influences of rotation excitation （j = 0 -3） on stereodynamics are discussed. The obtained stereodynamical information is compared with the previously reported results on the 2A′ and 2^A＂ PESs to give a full insight into the chemical stereodynamics of the title reaction.展开更多
Electron probe microanalysis and SEM were employed to study the phase equilibria and diffusion paths in C Ni 8Ta, C Ni 3Ta, C Ni 2Ta diffusion couples after annealed at 1100 ℃ for 120 h or at 1200 ℃ for 120 h ...Electron probe microanalysis and SEM were employed to study the phase equilibria and diffusion paths in C Ni 8Ta, C Ni 3Ta, C Ni 2Ta diffusion couples after annealed at 1100 ℃ for 120 h or at 1200 ℃ for 120 h and then at 1100 ℃ for 24 h. Attempt was made to use the calculated stability diagram of carbon activity to explain the experimental observations. The phases formed in the diffusion layers were all in the prediced ranges.展开更多
