Scientific paper

Observations of mean pulse shapes and pulse energies are reported for 38 pulsars at 2.7 and 4.9 GHz and for 7 of these at 10.7 GHz. The observational system and procedure are described and average pulse profiles are presented for 35 pulsars. These observations are compared with similar observations at lower frequencies. It is shown that the 3 dB width of pulse profiles decreases with increasing frequency in most cases, while the component separations either increase or decrease and may be characterized by a critical frequency correlated with the cutoff frequency in the spectra of the corresponding pulsars.
