Özet

We calculate the Bogolubov coefficients for a C((0)) metric which describes the snapping of a cosmic string. In this background, we show that there are no regular solutions with particle interpretation, but we find a generalized solution with integrable discontinuity, which exhibits particle creation. We also find a regular solution if we allow wave packets.
