ANALYSIS
OF A RESONATOR'S MOTION
momentum fluctuations
are
discernible in
the
former,
which,
in
the
case
of
short-wave
radiation of
low
density,
enormously
overwhelm
those obtained
from
the
theory.11

What
is
essentially new
in
the
present paper
is
the
circumstance
that the
momentum fluctuations have
been
exactly
calculated for
the
first time.
