We evaluate for the first time the femtoscopic correlation function to study the interaction. We find it extremely sensitive to the value of the scattering length, for which at present there exists only very limited information, not even knowing its sign. The measurement of this correlation function would provide much valuable information on the interaction, which could then also be used to settle the issue of possible 
nucleus bound states, an issue attracting much attention in the nuclear physics community.
