The principle and technique details of recoil ion momentum imaging are discussed and summarized. The recoil ion momentum spectroscopy built at the Institute of Modern Physics (Lanzhou) is presented. The first results obtained at the setup are analyzed. For 30 keV He2+ on He collision, it is found that the capture of single electron occurs dominantly into the first excited states, and the related scattering angle results show that the ground state capture occurs at large impact parameters, while the capture into excited states occurs at small impact parameters. The results manifest the collision dynamics for the sub-femto-second process can be studied through the techniques uniquely. Finally, the future possibilities of applications of the recoil ion momentum spectroscopy in other fields are outlined.

We performed the CO2 fragmentation experiment in Reaction Microscope, aiming to distinguish the variousdissociation mechanisms of (CO2)3+ions. By coincidently detecting the C+/O+/O+ ions, the Newton plot representingthe momentum relation among the three ions[1], as well as the Kinetic Energy Release (KER) distributionof sequential dissociation (which is the sum of the kinetic energies of all fragment ions), are *** displayed in Fig. 1, there are two parts in Newton plot, the bright areas represent the C+ ion taking smallkinetic energy and two O+ ions flying back to back approximately.

By analyzing the formation mechanism of a supersonic gas jet,a set of equations which describe the atomic beam properties were established. The influence of initial temperature,initial pressure,background gas pressure and pumping speed was discussed in detail. A simulation program was developed based on the equations,and the results under different initial conditions were obtained. The results are in good agreement with the experimental data,and suggest that,in order to get much smaller transverse momentum in collision experiments,it is necessary to lower the initial temperature and the initial pressure of the supersonic gas jet,together with increasing the pumping speed. These results are very instructive for construction of a new generation of cold supersonic gas jets.
