The formation of ultra-compact X-ray binaries (UCXBs) has not been wellunderstood. Previous works show that ultra-short orbital periods ($<1$ hr) maybe reached through mass transfer driven by magnetic braking in normallow/intermediate-mass X-ray binaries (L/IMXBs) only for an extremely smallrange of initial binary parameters, which makes it difficult to account for therather large population of UCXBs. In this paper we report the calculatedresults on mass transfer processes in L/IMXBs with a circum-binary disk. Weshow that when the orbital angular momentum loss due to a circum-binary disk isincluded, ultra-short orbital periods could be reached for a relatively widerange of initial binary parameters. The results of our binary models suggest analternative formation channel for UCXBs.
