  In this paper we explain the photoelectric effect in a variant of the
standard model of non relativistic quantum electrodynamics, which is in some
aspects more closely related to the physical picture, than the one studied in
[BKZ]: Now we can apply our results to an electron with more than one bound
state and to a larger class of electron-photon interactions. We will specify a
situation, where ionisation probability in second order is a weighted sum of
single photon terms. Furthermore we will see, that Einstein's equality
\[E_{kin}=h\nu-\bigtriangleup E>0\] for the maximal kinetic energy $E_{kin}$ of
the electron, energy $h\nu$ of the photon and ionisation gap $\bigtriangleup E$
is the crucial condition for these single photon terms to be nonzero.
