Resumo

The search for weak components outside the main pulse (MP) in the radiation of pulsars at a frequency of 110 MHz observed on the LPA LPI telescope in the Pushchino Multibeam Pulsar Search (PUMPS) has been carried out. The sample included 96 pulsars, for which the signal-to-noise ratio ( S/N) in the main pulse of the average profile during accumulation over 10 years was more than 40. It was found that PSR J1543+0929 has radiation for almost the entire period. The profile is three-component. The relative amplitudes of the lateral weak components are 0.013 and 0.025. For PSR J2234+2114, a precursor was detected that is 53◦ away from the MP.
