Scientific paper

A possible association between pulsar 2334 + 61, with a relatively long period of 0.5 s, and G114.3 + 0.3, a fairly old SNR is reported. The flat spectral index of -0.36 +/- 0.03 and large fractional polariazation suggest that the radio emission is powered by the pulsar. If so, the pulsar must have been born with a relatively short period of less than 100 ms. As the SNR is not particularly unusual morphologically, there might be many more such SNRs containing pulsars that are not beamed towards us.
