摘要
By finding a 2147-s X-ray pulsation in the recently identified ROSAT source RX 1238-38 we confirm that it is a member of the intermediate polar class of cataclysmic variable. We analyse the spectral changes over the white dwarf spin cycle, but are unable to distinguish between competing mechanisms for the cause of the pulsation. RX 1238-38 has an anomalous ratio of spin period to orbital period, similar to that of EX Hya.
