Query: Effect of Level Statistics on Local Magnetism in Nanoscale Metallic
  Grains   Effect of level statistics on local electronic states and local magnetism in
nanoscale metallic grains with transition-metal impurity in the ballistic
regime is studied. It is shown that the mean occupation of local electron and
the local magnetic moment in nanoscale metallic grains with odd conduction
electrons are larger than those with even conduction electrons. The effect of
even-odd parity on the condition for the occurrence of local magnetic moment is
also discussed, it is found that the critical value $\rho_{d}(0)U_{c}$ for the
formation of local moment in nanoscale metallic grains is much smaller than
that in bulks. The dependences of the local spin susceptibility on size and the
Coulomb interaction are obtained. These results show that the level statistics
plays an important role for the local magnetism, it distinguishes the
properties of nanoscale metallic grains from those of small clusters and bulks.
