( 1 ) under the conditions of the sample cell , the application of pulsed laser pumping - detection technology , research Rb (62D) excitation the state atoms react with H2 collisions generated RbH molecule rovibrational level population number density distribution and average rotation energy, vibrational energy , the translational kinetic energy of the relative ratio . RbH (X1Σ) v = 0,1 population . Rotation with a statistical distribution contour with the pool temperature distribution close to get RbH the Boltzmann rotational temperature slightly lower than the temperature of the cell , and the vibrational temperature is high . v = 1 and v = 0 on the cloth ranking number ratio of about 0.69 , thereby obtaining RbH (X1Σ) rotational energy on average and the average vibration energy, effective energy obtained by the reaction of the average translational kinetic energy , the energy of these three relative the ratio lt ; fR gt ; : lt ; fV gt ; :
