Measurements of the Polarization of Protons from Deuteron Photodisintegration

Liu, F.F. ; Lundquist, D.E. ; Wiik, B.H. ;
Phys.Rev. 165 (1968) 1478-1482, 1968.
Inspire Record 944944 DOI 10.17182/hepdata.26514

The polarization of the proton produced by the photodisintegration of the deuteron has been measured at several angles for photon energies between 170 and 450 MeV. The polarization is found to be around -0.20 (Basel convention) for 90° c.m. and photon energies between 200 and 300 MeV. This is in reasonable agreement with a calculation by D. George based upon the Austern model. However, the calculation fails to explain the strong increase in polarization with increasing photon energies. At a photon energy of 450 MeV and 90° c.m. the proton polarization is as large as -0.60.

Measurement of Polarized Target Asymmetry in $\gamma d \to p n$ in the Photon Energy Region Between 0.3-{GeV} and 0.7-{GeV}

Ohashi, Y. ; Awaji, N. ; Hayashii, H. ; et al.
Phys.Lett.B 110 (1982) 441-444, 1982.
Inspire Record 176585 DOI 10.17182/hepdata.30974

The target asymmetry in γ d → pn has been measured at proton c.m. angles of 70°, 100° and 130° in the photon energies between 0.3 and 0.7 GeV. Results show relatively small asymmetry values in contrast to large proton polarizations. A phenomenological analysis by Ikeda et al. does not reproduce the present data, especially in the lower energy region.

Proton polarization in deuteron photodisintegration in the Δ(1232)-resonance region

Zybalov, A.A. ; Konovalov, O.G. ; Marekhin, S.V. ; et al.
Nucl.Phys.A 533 (1991) 642-650, 1991.
Inspire Record 1392876 DOI 10.17182/hepdata.36724

We report the results from measurements of proton polarization P , in the γ +D→p+n reaction at photon energies ranging from 200 to 350 MeV. The data obtained are compared with the measured analysing power A , of the reverse reaction and with model calculations. The assumption of the dominant contribution of isobar configurations in this region is on the whole confirmed by the present proton polarization measurements.

Measurement of the Proton Polarization in Deuteron Photodisintegration at Photon Energies Between 350-MeV and 700-MeV

Kamae, T. ; Arai, I. ; Fujii, T. ; et al.
Nucl.Phys.B 139 (1978) 394-412, 1978.
Inspire Record 135594 DOI 10.17182/hepdata.35048

The proton polarization in the γ d → pn reaction has been measured at a c.m. angle of 90° and photon energies between 350 and 700 MeV, using a carbon polarimeter. The magnitude of the polarization shows a sharp energy dependence with a peak of about −80% at around 500–550 MeV. This feature cannot be explained by conventional models and seems to indicate a new mechanism in the dibaryon system.

FURTHER MEASUREMENT OF PROTON POLARIZATION IN DEUTERON PHOTODISINTEGRATION AT PHOTON ENERGIES BETWEEN 400-MEV AND 650-MEV: POSSIBLE EVIDENCE FOR DIBARYON RESONANCES

Ikeda, H. ; Arai, I. ; Fujii, H. ; et al.
Nucl.Phys.B 172 (1980) 509-533, 1980.
Inspire Record 158986 DOI 10.17182/hepdata.34500

The proton polarization in deuteron photodisintegration has been measured at photon energies between 400 and 650 MeV at c.m. angles between 45° and 135°. To explain the polarization and differential cross-section data consistently, we have introduced dibaryon resonances and performed a partial-wave analysis at photon energies between 350 and 700 MeV. It has been shown that the existence of at least two dibaryon resonances is required in this energy range: one at ∼2380MeV with I ( J P ) = 0(3 + ) or 0(1 + ), and the other at ∼2260 MeV with I ( J P ) = 1(3 − ) or 1(2 − ).

Study on the cross section asymmetry of deuteron photodisintegration induced by low energy polarized γ quanta

Barannik, V.P. ; Gorbenko, V.G. ; Gushchin, V.A. ; et al.
Yad.Fiz. 38 (1983) 1108-1100, 1983.
Inspire Record 1408810 DOI 10.17182/hepdata.17732

Results are presented on measured asymmetry parameter in the cross sections of the deuteron photodesintegration by linearly polarized photon beam in the energy range 40-70 MeV for the proton emission angles of 75 and 90 deg in the c. m. s. The experimental data are compared with the theoretical calculations by Partovi, Arenhovel, as well as with calculations performed within an invariant approach with gauge-invariant amplitudes in the pole approximation. The results of the calculation by Arenhovel and the present calculations satisfactorily agree with the experimental data, while the Partovi theory does not describe the asymmetry parameter measurements for photon energies above 40 MeV
