INVESTIGATIONS ON THE ENERGY-TRANSFER OF EXCITED PARTICLE COLLISION WITH DOUBLE LASER LINES FOR EXCITATION OF LA(I)

Generally speaking, productions of thermally-assisted and stepwise fluorescence are the consequence of energy transfer caused by particle collision. In some circumstances, energy transfer caused by particle collision is considerably intense. We have ever used the fluorescence produced by energy transfer of particle collision to measure the branching ratios in the atomic transitions and acquired good results. To our knowledge, the systematic in
