摘要: The authors have studied, in a beam experiment, the energy pooling reaction between two laser excited Na*(3p) atoms, where final state one of Na atoms is 5s or 4d and other ground state. polarization can be varied by changing polarization. By using counterpropagating beams intersecting them twice (directly indirectly after reflection against mirror) collision partners independently. Since intersects at an angle 87.6 degrees , relative velocity furthermore selected exploiting Doppler effect. In authors' experiment relevant cross sections coherences, specified according to various magnetic substate combinations colliding determined.
