Rise and fall of the spin alignment in deep-inelastic reactions

Both the magnitude and alignment of the transferred angular momentum in the reaction Ho165+Ho165 have been measured as a function of Q value via continuum -ray multiplicity and anisotropy techniques. Two regimes are observed: A low Q-value regime where the aligned angular momentum component dominates over the random components, and a large Q-value regime where the random components dominate and decrease the spin alignment.
