MEASUREMENT OF THE DIFFERENCE IN P P TOTAL CROSS-SECTIONS FOR PURE PARALLEL AND ANTIPARALLEL TRANSVERSE SPIN STATES (DELTA SIGMA (T AT T(P) = 487-MEV, 639-MEV, AND 791-MEV

Inspire Record 192364 DOI 10.17182/hepdata.23817

The difference between total cross sections in pure transverse-initial-spin states for the p−p interaction has been measured at Tp=487, 639, and 791 MeV, using a frozen-spin target. A comparison with previous data and available phase-shift analyses is made.

SPIN DEPENDENT PARAMETERS P (NOOO), D (NONO), K (NOON), D (SOSO), D (SOKO), M (SOSN), AND M (SOKN) IN P P ELASTIC SCATTERING AT 579-MEV

Aprile, E. ; Hausammann, R. ; Heer, E. ; et al.
Phys.Rev.D 27 (1983) 2600-2616, 1983.
Inspire Record 195612 DOI 10.17182/hepdata.23816

The polarization parameter Pn000, the two-spin parameters Dn0n0, Kn00n, Ds0s0, and Ds0k0, and the three-spin parameters Ms0sn and Ms0kn have been measured for pp elastic scattering at 579 MeV between 34° and 118° center-of-mass scattering angle. The experiment was performed at SIN using a polarized proton beam, a polarized butanol target, and a polarimeter for the measurement of the polarization of the scattered proton. These data form the basis for a complete experimental determination of the scattering amplitudes.

Measurements of Spin Parameters in $p p$ Elastic Scattering at 6-{GeV}/$c$

Linn, S.L. ; Perlmutter, A. ; Crosbie, E.A. ; et al.
Phys.Rev.D 26 (1982) 550, 1982.
Inspire Record 11848 DOI 10.17182/hepdata.23900

We measured the differential cross section for proton-proton elastic scattering at 6 GeV/c, with both initial spins oriented normal to the scattering plane. The analyzing power A shows significant structure with a large broad peak reaching about 24% near P⊥2=1.6 (GeV/c)2. The spin-spin correlation parameter Ann exhibits more dramatic structure, with a small but very sharp peak rising rapidly to about 13% at 90°c.m.. This sharp peak may be caused by particle-identity effects.

STRUCTURE OBSERVED IN THE SPIN SPIN CORRELATION PARAMETER C(LL) = (L, L, 0, 0) IN P P ELASTIC SCATTERING AROUND THETA (C.M.) = 90-DEGREES IN THE REGION P(LAB) = 2.5-GEV/C - 5.0-GEV/C

The spin-spin correlation parameter CLL=(L, L; 0, 0) has been measured for p−p elastic scattering around θc.m.=90° up to plab=5 GeV/c. An interesting energy dependence is observed in CLL and the results are interpreted by comparison with other available data.

SPIN DEPENDENCE IN NEUTRON PROTON CHARGE EXCHANGE AT 790-MEV

Ransome, R.D. ; Hollas, C.L. ; Riley, P.J. ; et al.
Phys.Rev.Lett. 48 (1982) 781-784, 1982.
Inspire Record 180615 DOI 10.17182/hepdata.20595

The analyzing power A and spin-transfer parameters KNN, KSS, KSL, and KLL have been measured in the np charge-exchange (np→pn) region at 790 MeV. These data provide new and unique information on the spin dependence of the np interaction in the charge-exchange region. Models which explain the charge-exchange peak in the np elastic differential cross section as being due to interference between one-pion exchange and a slowly varying background are in basic agreement with the data.

Measurement of $\Delta - \sigma_L$ in Proton Proton Scattering Between 300-{MeV} and 800-{MeV}

Phys.Rev.D 24 (1981) 2008, 1981.
Inspire Record 10751 DOI 10.17182/hepdata.51322

We have measured the difference between proton-proton total cross sections for parallel and antiparallel longitudinal spin states [ΔσL=σtot(⇄)−σtot(⇄)] at 13 incident energies between 300 and 800 MeV, which cover the region of possible D21 and F33 diproton resonances. The present experiment has strongly confirmed the structure previously observed at the Argonne Zero Gradient Synchrotron. No additional narrow structure has been found.

Measurement of the Difference in $P N$ Total Cross-sections in Pure Longitudinal Spin States

Phys.Rev.Lett. 46 (1981) 1177-1180, 1981.
Inspire Record 170180 DOI 10.17182/hepdata.20657

The total-cross-section difference in pure longitudinal spin states for p−d interactions has been measured at momenta from 1.1 to 6 GeV/c. Spin-dependent Glauber-type corrections and other corrections have been made to obtain ΔσL(pn) and ΔσL(I=0). These measurements are of fundamental interest and will also help in determining the existence and nature of dibaryon resonances.
