Scientific paper

The letter reports results of a search for periodicities on time scales of minutes in the flux from eight X-ray sources. Evidence is found for regular modulations in the sources 3U 1223-62, 3U 1728-24, and 3U 1813-14, with periods of 11.6, 4.3, and 31.9 minutes, respectively. In the case of the latter two sources, the modulation observed could be the alias of the true modulation which is beyond the Nyquist frequency of the data. The modulation periods of both 3U 1223-62 and 3U 1728-24 are variable. A measurement of the X-ray column density of 3U 1728-24 supports its suggested identification with a heavily reddened star in the X-ray error box.
