| Abstract: | We made a period folding analysis on two sets of COS-B observations and obtained a clearly pulsed phase structure in the γ-ray photons from the direction of PSR 0740-28. The phase diagrams from the two different data sets have a similar structure and the period and period rate are close to radio expectations. The probability of the two phase structures arising by chance is less than 2×10−5. Hence we believe PSR 0740-28 is a new γ-ray pulsar. |
