  The first experimental results of a new quantum method for calculating
nuclear temperature and density of fragmenting heavy ions is presented. This
method is based on fluctuations in the event quadrupole momentum and fragment
multiplicity distributions of light Fermions. The cal- culated temperatures are
lower than those obtained with a similar classical method. Quenching of the
normalized multiplicity distributions of light fermions due to Pauli blocking
is also observed. These results indicate a need for a quantum treatment when
dealing with statistical properties of fragmenting heavy-ions.
