pp Scattering-Amplitude Measurements and a Possible Direct-Channel Resonance in pp System

  • A. Yokosawa
Part of the Studies in the Natural Sciences book series (SNS, volume 12)


In this talk I would like to discuss our results of pp elastic scattering with various spin combinations of polarized beams and polarized targets. Since experimental details have been described in our published articles,1,2,3 I will minimize my discussion.
