ABSTRACT PSR1237 + 25, one of the first pulsars to be discovered1,2, is characterized by a striking five-peaked integrated intensity profile. Like many other pulsars, PSR1237 + 25 also

exhibits the puzzling phenomena of drifting subpulses, ‘nulling’ and ‘mode-switching’. The period of pulsation is 1.38 s, but the radio-emission occurs within an 80 ms interval. We have

analysed single-pulse data from this pulsar at 430 MHz to throw light on the still obscure mechanism of pulsar emission. We conclude that the behaviour of PSR1237 + 25 can be explained on

the polar-cap model if regular short (S) bursts spiralling in towards the magnetic pole are occasionally interrupted by long (L) bursts along the magnetic axis. Access through your
