Abstract

We apply the new variational principle of Balian and Veneroni to calculate the fluctuations in final-fragment mass, charge, and kinetic energy for the systems ${}^{16}O$ + ${}^{16}O$ ( $E_{lab} - 160$ MeV) and ${}^{40}{Ca}$ + ${}^{40}{Ca}$ ( $E_{lab} = 278$ MeV). The calculated fluctuations are larger than conventional time-dependent Hartree-Fock results and, in the latter case, are consistent with the experimental fragment mass distribution.
