    "abstract": "We investigate in a simple model whether a Jastrow-based approach for a\nmany-body system containing two-body interactions can be exact. By comparison\nwith recent assertions to the contrary, we find that in general the exact wave\nfunction is \\emph{not} purely two-body correlated. Nonetheless, we show that\nthe energy estimate obtained from the calculations is as accurate as it can\npossibly be, suggesting why Jastrow wave functions are such a good choice.",
