We have selected Abell 3266 to search for ram-pressure induced star formationas a global property of a merging cluster. Abell 3266 (z = 0.0594) is a highmass cluster that features a high velocity dispersion, an infalling subclusternear to the line of sight, and a strong shock front. These phenomena should allcontribute to making Abell 3266 an optimum cluster to see the global effects ofRPS induced star formation. Using archival X-ray observations and publishedoptical data, we cross-correlate optical spectral properties ([OII, H$\beta$]),indicative of starburst and post starburst, respectively with ram-pressure,$\rho$v$^{2}$, calculated from the X-ray and optical data. We find thatpost-starburst galaxies, classified as E+A, occur at a higher frequency in thismerging cluster than in the Coma cluster and at a comparable rate tointermediate redshift clusters. This is consistent with increased starformation due to the merger. However, both starburst and post-starburstgalaxies are equally likely to be in a low or high ram pressure environment.From this result we infer that the duration of the starburst phase must be verybrief so that: (1) at any time only a small fraction of the galaxies in a highram pressure environment show this effect, and (2) most post-starburst galaxiesare in an environment of low ram pressure due too their continued orbitalmotion in the cluster.
