Space Star (SS) anomaly in Nd breakup cross section is well known. SS anomaly has large charge asymmetry; exp eriment is larger than calculation at nd SS and exp eriment is smaller than calculation at pd SS. There are also rep orts on anomaly in quasi-free scattering (QFS) cross section in Nd breakup reaction. At nd QFS, exp erimental cross section was found to be larger than calculation. On the contrary, pd QFS cross section measured by Köln group is smaller than pd calculation. We measured QFS cross section in pd breakup reaction, and compared the data with recent pd calculations to see angular dep endence of QFS anomaly.
