Purpose: Due to the significant increase of a number of pulsars discovered with high-frequency radio telescopes over the last ten years and the necessity to obtain accurate parameters of their decameter radiation (as well as to identify single pulses detected with the UTR-2), the second decameter census of these sources with the UTR-2 radio telescope became needed. Design/methodology/approach: Single pulses detected as a result of the first decameter survey of pulsars and transient emission sources can be anomalously intense pulses of the recently discovered pulsars. Identification is only possible with an accurate information on the dispersion measure (DM) of each of these sources. Given that the new pulsars are likely to have a low radiant flux density, in contrast to the first decameter pulsar census 1, the second one plans to increase the signal-to-noiseratio by increasing the observation time of each pulsar. This paper gives a complete list of the studied sources, limited by the dispersion measure (DM 0.1 s) and declination (δ>-10 º ), known for the beginning of 2020, as well as some examples of the decameter pulsar radio emission detected by means of pipeline data processing with the possibility of flexible adjustment of search parameters. Findings: For the first time in the low-frequency wavelength range, the radio emission from the PSR J2325-0530, PSR J0613+3731, and PSR J1426+52 pulsars has been detected. The main result of present work is specified period for the latter pulsar (PSR J1426+52), being 0.995866 s ± 5 µs, the other parameters of its radio emission are also specified. Conclusions: High sensitivity of the UTR-2 radio telescope, its receiving equipment and efficient data processing and analysis pipeline allow detecting the decameter radiation of weak pulsars, as well as obtaining their parameters with the accuracy sufficient for identification of previously discovered transient signals.
