摘要：

We detected giant pulses from the pulsar PSR B1112+50. A pulse with an intensity that is a factor of 30 or more higher than the intensity of the average pulse is encountered approximately once in 150 observed pulses. The peak flux density of the strongest pulse is about 180 Jy. This value is a factor of 80 higher than the peak flux density of the average pulse. The giant pulses are narrower than the average profile by approximately a factor of 5 and they cluster about the center of the average profile. (C) 2003 MAIK "Nauka/Interperiodica".
