    Survey on polarization observables in deuteron photodisintegration below pion-production threshold (1991)
    Springer
    Few body systems 11 (1991), S. 33-72 
    Details
    ISSN: 1432-5411
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Polarization observables of deuteron photodisintegration with polarized photons and oriented deuterons are systematically investigated below π-production threshold with respect to their sensitivity to subnuclear degrees of freedom and relativistic effects, to the different electric and magnetic multipole contributions, and to various realistic potential models. In particular, a complete survey on all single- and double-polarization observables like beam and target asymmetries of the differential cross section, nucleon polarization and proton-neutron spin correlation is given.

    Deuteron photodisintegration at low energies (1991)
    Springer
    Few body systems 10 (1991), S. 105-133 
    Details
    ISSN: 1432-5411
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract All presently available experimental data on deuteron photodisintegration below 40 MeV (i.e., total and differential cross sections, photon asymmetry and neutron polarization) are collected and carefully compared with the present status of the conventional theory (i.e., in the framework of mesontheoretical or semi-phenomenologicalN-N potentials including subnuclear degrees of freedom and relativistic corrections). No significant evidence for a failure of the conventional theory is found within the present experimental accuracy.

    Heavy-mesons exchange and the backward deuteron electrodisintegration (1992)
    Springer
    Few body systems 11 (1992), S. 155-170 
    Details
    ISSN: 1432-5411
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Backward electrodisintegration of the deuteron is calculated using an exchange-current operator containing π, η, ρ, ω, δ, σ, andA 1 exchanges. The deuteron and1S0 np wave functions are derived from the Bonn OBEPs. For completeness, we introduced theA 1-meson exchange into the OBEP's as well. As a consequence, the value ofD-state probabilityP D is increased by 0.2%–0.8%. The computed cross sections are compared with new data.

    Relations between polarization observables and complete sets for deuteron photodisintegration (1990)
    Springer
    Few body systems 8 (1990), S. 77-93 
    Details
    ISSN: 1432-5411
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The polarization observables for deuteron photodisintegration are given as Hermitean forms of theT-matrix elementst i . By inversion we are able to express a given productt i * t j in terms of polarization observables. This allows (i) to derive linear relations between observables for unpolarized, circularly and linearly polarized photons, (ii) to construct explicitly complete sets of polarization observables, and (iii) to derive quadratic relations between observables.
