Abstract
Relationships are obtained connecting the two-nucleon overlap function of t he eigenstates in the (A - 2) particle system with the asymptotic behavior of the two-body density matrix for the ground state of the A-particle syste m. This makes it possible to calculate the two-body overlap functions, spec troscopic factors and separation energies on the basis of a realistic two-b ody density matrix. The procedure can be used in describing the (e,e'NN) an d (gamma,NN) reactions where the two-body overlap functions are a key ingre dient in the analysis. [S0556-2813(99)01602-7].
