  Title: THE X-RAY SPECTRUM OF $\ALPHA$ CEN                                              


Abstract:
 We propose to obtain an X-ray spectrum of the nearest solar-like star $\alpha$
 Centauri. Unlike most stars observed by ASCA, which are {\bf active} stars, $\alpha$
 Centauri is an {\bf inactive} star with a corona, similar to that of our Sun..From
 EUV observations we know the presence of iron in ionisation stages up to Fe XVIII in
 the corona of $\alpha$ Centauri. The purpose of the ASCA observations is to detect
 Fe XVII lines, which are very strong in the X-ray band, but weak in the EUV band, a
