Abstract As a possible model for low-mass X-ray binaries in globular clusters and in the galactic bulge, the evolution of a stripped giant-neutron star binary system is investigated. The systems are characterized by masses less than 2.2 solar masses and periods greater than 0.766 days. It is found that mass transfer driven by nuclear evolution yields rates greater than or approximately equal to 10 to the -9th solar mass per yr for helium-core masses greater than or approximtely equal to 0.2 solar mass. The mass transfer rate varies slowly throughout until it abruptly ceases at the point when the stellar radius rapidly contracts from its critical Roche surface. The high mass transfer rates refect the more rapid stellar expansion associated with the giant in a more evolved state. Because the stellar radius is large in such models, the expected binary orbital periods are greater than or approximately equal to 1 day.
