Random-test multipole analysis of two-body image and image reactions of 4He nuclear disintegration Original Research Article

The angular dependence of azimuthal asymmetry of cross sections for the 4He(View the MathML source)T and 4He(View the MathML source)3He reactions was measured at linearly polarized photon energies of 40, 60 and 80 MeV. With the data obtained as the basis and using the previously measured differential cross sections, a multipole analysis of the reactions was performed in the E1, E2 and M1 approximation. The cross sections for the multipole transition and their errors were estimated by multiply solving the set of equations that relate the Legendre coefficients to the multipole amplitude moduli. Cross sections for spin S=1 transitions of the final-state particles were determined.
