Abstract
By finding a 2147-s X-ray pulsation in the recently identified ROSAT s ource RX 1238-38 we confirm that it is a member of the intermediate po lar class of cataclysmic variable. We analyse the spectral changes ove r the white dwarf spin cycle, but are unable to distinguish between co mpeting mechanisms for the cause of the pulsation. RX 1238-38 has an a nomalous ratio of spin period to orbital period, similar to that of EX Hya.
