Lamb shift
noun
(quantum
mechanics,

electrodynamics)
A
small
difference
between
the
energy
levels
2S_½
and
2P_½
of
the
hydrogen
atom,
not
predicted
by
the
Dirac
equation,
whose
detection
in
the
Lamb–Retherford
experiment
of
1947
foreshadowed
the
development
of
quantum
electrodynamics
(in
which
the
discrepancy
is
explained
to
be
an
effect
of
the
emission
and
re-absorption
of
virtual
photons);
such
a
difference
between
otherwise
expectedly
equal
energy
levels
of
hydrogen
or
any
other
type
of
atom.
