Abstract :

we reported the detection of a 0.3162 Hz QPO for the first time in the transient pulsar 4U 1323–619. These newly detected QPOs were present more frequently in decline phase of outbursts as compare to the rising phase. However, there are only very few cases of accretion–powered X–ray pulsar such as SMC X–1 (Wojdowski et al. 1998), Her X–1, 4U 1626–67, LMC X–4 (see Table 1 of Shirakawa & Lai 2002) and 4U 0115+63 where multiple QPOs are seen. Another unique thing we detected in this work is the presence of multiple QPOs simultaneously in the same observation at three occasions.
