<P>
This  option allows fractional occupation of the molecular orbitals.
A Gaussian broadening function of exponent <TT>smear</TT> is used as described in 
the paper:
R.W. Warren RW and B.I. Dunlap, Chem. Phys. Letters <B>262</B>, 384 (1996).

The user must be aware that an additional energy term is added to the total
energy in order to have
energies and gradients consistent.
