  We present the discovery of PSR J1410-6132, a 50-ms pulsar found during a
high-frequency survey of the Galactic plane, using a 7-beam 6.3-GHz receiver on
the 64-m Parkes radio telescope. The pulsar lies within the error box of the
unidentified EGRET source 3EG J1410-6147, has a characteristic age of 26 kyr
and a spin-down energy of 10^37 erg s^-1. It has a very high dispersion measure
of 960+/-10 cm^-3 pc and the largest rotation measure of any pulsar, RM=+2400
+/- 30 rad m^-2. The pulsar is very scatter-broadened at frequencies of 1.4 GHz
and below, making pulsed emission almost impossible to detect. Assuming a
distance of 15 kpc, the pulsar's spin-down energy and a gamma-ray efficiency
factor of ~10 per cent is sufficient to power the gamma-ray source. We
therefore believe we have identified the nature of 3EG J1410-6147. This new
discovery suggests that deep targeted high-frequency surveys of inner-galaxy
EGRET sources could uncover further young, energetic pulsars.
