Evidence for short-range correlations in O-16

The reaction O-16(e,e'pp)C-14 has been investigated at three values of the transferred energy omega. The differential cross sections were determined a s a function of the missing energy and the missing momentum. Evidence for s hort-range correlations in O-16 has been obtained from the transition to th e ground state of C-14. The cross sections for this transition are well rep roduced by two independent parameter-free microscopic calculations. The res ults of both calculations show that the reaction is dominated by knockout o f a proton pair in a S-1(0) state, driven by short-range-correlations. (C) 2000 Published by Elsevier Science B.V.
