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.
