Exclusive Electro-Disintegration of 3He at high Q2: II. Decay Function Formalism

Original · EN

Based on the theoretical framework of generalized eikonal approximation we study the two-nucleon emission reactions in high Q² electro-disintegration of ³He. Main aim is to investigate those features of the reaction which can be unambiguously identified with the short range properties of the ground state nuclear wave function. To evaluate the differential cross section we work in the formalism of the decay function which characterizes the property of the ground state wave function as well as the decay properties of final two nucleon spectator system. Our main motivation here is to explore the accessibility of two-- and three--nucleon short range correlations in ³He as well as to isolate unambiguously single and double rescattering processes in the reaction dynamics. Our analysis allowed us also to identify new approaches for investigating the role of the practically unknown three-nucleon forces in the ground state wave function of ³He.
