英文摘要The results of asca observations of rx j1838.4-0301 are presented. the source was found to be faint and there was no obvious x-ray flare during the asca observation. no evidence for pulsations was found near to the 5.45 s period previously reported from rosat observations. the source energy spectrum cannot be fitted well with either a single-component power law, thermal bremsstrahlung, or blackbody emission model, while a variety of two component models do give acceptable fits. the flux which we derive is consistent with that measured in the quiescent state with rosat. on the basis of the rosat and asca results, we suggest that rx j1838.4-0301 may be a transient source in which the quiescent state has a fairly constant flux level. however, our results do not yet enable a clear determination of whether this source is an anomalous x-ray pulsar or some other type of object.
