Binary-single star interactions in globular clusters

An extensive series of three-body interactions involving hard binaries and single stars are calculated by direct integration of ∼10 5 encounters. Unlike previous calculations, the stars have different mass ratios, chosen to be representative of the stellar and remnant population in a globular cluster, and most effort was devoted to the difficult case of hard binaries, the most likely primordial binaries to survive in a cluster. Graphs, tables and analytical fits to differential and integral cross sections for properties of different interaction channels are presented and discussed
