Description
We proposed the experiment for measuring the spin observables, Ab, At and Ann in elastic pp scattering by using the both normally polarized proton beam and target at momentum p = 45 GeV/c. Such study will allow us to test experimentally the equality of polarization P to analysing powers AN. This equality was theoretically proved and widely used for extraction the polarization observables with unpolarized beam and polarized target. The polarization and analysing power at high energy are rapidly decreasing. Therefore, the recoil proton polarization was measured by using the double scattering schema. For determination P, An and Ann one needs to use the polarized beam and polarized target in the one scattering schema. But such experiments are very scarce. There are no the experimental data on the spin correlation parameter Ann in diffractive region at the momentum more than 12 GeV/c.
