Abstract

Space Star anomaly in Nd breakup reaction below 20 MeV is well-known. Also, Quasi-Free Scattering (QFS) anomaly in Nd breakup reaction below 40 MeV has been reported from several experiments. Origin(s) of QFS anomaly has not been known, similarly to origin(s) of SS anomaly. We have been making a systematic measurement on pp-QFS cross section, previously at E_p = 9. 5 MeV and 13 MeV and recently at 7. 5 and 19 MeV. We used an unpolarized p-beam to correctly measure only cross section. Our data agreed well with pd calculation by A. Deltuva. So far, no pp-QFS anomaly has been found in our experiments.
