Measurement of inclusive momentum spectra and multiplicity distributions of charged particles at $\sqrt{s}\sim 2–5\mathrm{GeV}$

Inclusive momentum spectra and multiplicity distributions of charged particles measured with the BESII detector at center of mass energies of 2.2, 2.6, 3.0, 3.2, 4.6 and 4.8 GeV are presented. Values of the second binomial moment $R_2$ obtained from the multiplicity distributions are reported. These results are compared with both experimental data from high energy $e^{+}{e}^{-},$ ep, and $p\overline{p}$ experiments and QCD calculations.
