<dt>Description</dt>
<dd>We present an exactly solvable example of a non-stationary system, which has an inertial and an uniform accelerated asymptotic region. We construct a set of solutions that are quasi-classical in these two regions and compare the two sets. The Bogoliubov-coefficients have thermal character and show a temperature of &lt;math&gt;a_\infty /2 \pi \,\!&lt;/math&gt;, where &lt;math&gt;a_\infty \,\!&lt;/math&gt; is the asymptotic acceleration in the out-region. This result is much what one would expect on the grounds of the Hawking-effect. It implies that the natural particle number is not conserved in free Minkowski-space.</dd>
