Limitation of linear momentum transfer in heavy-ion reactions

Angular correlations of fragments from 292-MeV-${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$-induced fission of ${}_{}{}^{165}{}_{}{}^{}\mathrm{Ho}$, ${}_{}{}^{181}{}_{}{}^{}\mathrm{Ta}$, ${}_{}{}^{197}{}_{}{}^{}\mathrm{Au}$, ${}_{}{}^{209}{}_{}{}^{}\mathrm{Bi}$, and ${}_{}{}^{238}{}_{}{}^{}\mathrm{U}$ have been measured. The correlations are interpreted in terms of a full linear momentum transfer component and several components with less than full momentum transfer. The maximum angular momentum $l_{\mathrm{FLMT}}$, associated with the full linear momentum transfer component from these and other previous angular correlation measurements, as well as from velocity measurements of evaporation residues, corresponds to rolling heavy ion collisions.
