Three-Body Correlations In $^{6}$He Revealed In The Quasi-Free Knockout Reaction $^{4}He($^{6}$He,2$\alpha$)2n
International audience The 4He(6He,2$\alpha$)2n reaction was studied in experiments designed for the observation of a quasi-free scattering (QFS) occurring between the $\alpha$ core of the Borromean 6He nuclei and the 4He target nuclei. The helium gas target cooled down to 14 K was bombarded by a 25...
