Query: Measurement of the vector and tensor analyzing powers for dp- elastic
  scattering at 880 MeV   The vector Ay and tensor analyzing powers Ayy and Axx for dp- elastic
scattering were measured at Td = 880 MeV over the c.m. angular range from 60 to
140 degrees at the JINR Nuclotron. The data are compared with predictions of
different theoretical models based on the use of nucleon-nucleon forces only.
The observed discrepancies of the measured analyzing powers from the
calculations require the consideration of additional mechanisms.
