Description
A quantum Schwarzschild black hole is described, at the mini
super spacetime level, by a non-singular wave packet composed
of plane wave eigenstates of the momentum Dirac-conjugate to
the mass operator. The entropy of the mass spectrum acquires
then independent contributions from the average mass and the
width. Hence, Bekenstein's area entropy is formulated using the
{mass}^2 average, leaving the {mass} average to set the Hawking
temperature. The width function peaks at the Planck scale for an
elementary (zero entropy, zero free energy) micro black hole of
finite rms size, and decreases Doppler-like towards the classical
limit.
