    PR # 32063                                                                   
     Spectroscopy of LMXRB in the soft X-ray band have yielded a number of       
     important results, among which the data obtained with the Einstein          
     OGS and EXOSAT TGS grating, and the Einstein SSS stand out.  Recently       
     the discovery in the X-ray spectra of the LMXRB pulsar 4U1626-67 of         
     the 1 keV line,identify with L-alpha NeX,implies an over-abundance of       
     Neon which has major evolutionary implication for the composition of        
     the companion star. ASCA also separated the low energy complex              
     detected first with the SSS in another similar LMXRB XB0614+09.We           
     propose to use ASCA to observe a sample of LMXRB having faint optical       
     counterparts and use the low energy line emission properties to             
     identify evolutionary class of the system.The study of such a sample        
    could led to better understand
