Pre-Emission Of Alpha-Particles In Deep-Inelastic Reactions
PHYSICAL REVIEW LETTERS(1979)
摘要
In-plane angular and energy correlations between $\ensuremath{\alpha}$ particles and heavy ejectiles have been measured for the reaction $^{14}\mathrm{N}$ + $^{58}\mathrm{Ni}$ at 148 MeV. The coincidence cross sections may be parametrized as a product of singles cross sections for the detection of $\ensuremath{\alpha}$ particles and heavy ejectiles. The observed correlations indicate that the $\ensuremath{\alpha}$ particles are emitted at an early stage, prior to the formation of the deep-inelastic fragments.
