We present the results of recent Arecibo and Green Bank observations of the globular cluster NGC 6760 .
Using Arecibo , a phase-coherent timing solution has been obtained for the previously known binary pulsar in this cluster , PSR J1911+0102A .
We have also discovered a new millisecond pulsar in NGC 6760 , PSR J1911+0101B , an isolated object with a rotational period of 5.38 ms and a dispersion measure { DM } = 196.7 cm ^ { -3 } pc .
Both pulsars are located within 1.3 core radii of the cluster center and have negative period derivatives .
The resulting lower limits for the accelerations of the pulsars are within the range expected given a simple model of the cluster .
A search for eclipses in the PSR J1911+0102A binary system using both telescopes yielded negative results .
The corresponding limits on the extra gas column density at superior conjunction are consistent with the hypothesis that the observational properties of ultra-low-mass binary pulsars like PSR J1911+0102A are strongly affected by the inclination of the orbital plane of the system .
Among globular cluster pulsar populations , that of NGC 6760 exhibits one of the largest known spreads in DM .
This quantity seems to be roughly proportional to a cluster ’ s central DM ; this suggests that the observed spread is caused by a turbulent interstellar medium at spatial scales of 1 pc .
