| Abstract: | Observables that related to the impact parameters in intermediate and relativistic energy heavy ion reactions were introduced. These observables that related to the impact parameter include linear momentum transfer, multiplicities of charged particles, the ratio of transverse kinetic energy and longitudinal kinetic energy Erat, the transverse momentum directivity, Zbound, elliptic flow etc. Impact parameter determination for intermediate and relativistic energy heavy ion reactions was presented. The reliabilities of the methods of parameter determination were discussed. |
