(gzipped) PostScript## Gravitation wave emission from radio pulsars revisited
We report a new pulsar population synthesis based on Monte Carlo
techniques, aiming to estimate the contribution of galactic radio
pulsars to the continuous gravitational wave emission. Assuming that
the rotation periods of pulsars at birth have a Gaussian distribution,
we find that the average initial period is 290 ms. The number of
objects with periods equal to or less than 0.4 s, and therefore
capable of being detected by an interferometric gravitational antenna
like VIRGO, is of the order of 5100-7800. With integration times
lasting between 2 and 3 yr, our simulations suggest that about two
detections should be possible, if the mean equatorial ellipticity of
the pulsars is =10
