英文摘要We present periodicity and single-pulse searches at 1250 MHz for 22 "radio-quiet" gamma-ray pulsars, conducted using the Five-hundred-meter Aperture Spherical Radio Telescope. For PSR J1813-1246, we successfully detected pulsed signals with a spin period of 48.08 ms and a dispersion measure of 209.85 pc cm-3, consistent with the spin period measured at gamma-ray wavelengths. The estimated flux density is approximately 9 mu Jy. For the remaining 21 sources, no radio emission was detected, with flux density upper limits of several mu Jy. The capability to detect pulsars with such low flux densities provides the opportunity to determine if and how these faint sources differ from much radio-brighter pulsars.
