Based on a Boltzmann equation, the transverse momentum distributions are calculated for central {sup 40}Ar+{sup 51}V collisions with an aim to determine the in-medium nucleon-nucleon cross section. Indeed, the calculations suggest that measurements of the energy of balance, {ital E}{sub bal}, can provide a powerful tool to pin down the in-medium nucleon-nucleon cross section. Within our improved Boltzmann-Uehling-Uhlenbeck (BUU) model, the in-medium nucleon-nucleon cross section is narrowed down to {sigma}{sub {ital N}{ital N}}{approx}30--40 mb, for the first time, using recent experimental data.
