THE BINARY PULSAR PSR-1908+00 IN NGC-6760

We present orbital parameters of the 3.6 ms binary pulsar 1908 + 00 in the globular cluster NGC 6760. The orbital period is 3.4 hr, and the mass function is 3 x 10(-6) M., implying a minimum companion mass of 0.018 Me.. The companion is probably degenerate; and if it is hydrogen, it is close to overflowing its Roche lobe. The only other millisecond binary radio pulsar systems with orbital period <10 hr and mass function below 10(-3) M. are the eclipsing pulsars 1957 + 20 and 1744-24A, and the very low mass binary 0021 - 72J. These pulsars are ablating their companions and may be the progenitors of isolated millisecond pulsars. PSR 1908 + 00 shows no evidence for long-duration eclipses as are seen in 1744-24A, but short-duration eclipses as in 1957 + 20 are not excluded.
