Cross section of pd breakup at Star configuration (equilateral triangle) was systematically measured at E = 9.5 and 13 MeV/A with varying an angle α between the Star plane and the beam axis. At 13 MeV/A, Star anomaly appears only around Space Star (α = 90°) configuration. At 9.5 MeV/A, same feature was found in our experimental data at α = 0°-105°, but large difference of about -25% at α = 124°-180° was reported by Köln group.
