Neutron-neutron scattering length from the ${}^6$He$(p,p\alpha )nn$ reaction

Matthias Göbel, Thomas Aumann, Carlos A. Bertulani +3

We propose a novel method to measure the neutron-neutron scattering length using the ${}^6$He$(p,p\alpha )nn$ reaction in inverse kinematics at high energies. The method is based on the…
