Spectroscopy of $^{9}$He, quasi-free scattering $^{6}$He+$^{4}$He

Abstract : Low lying states of the unbound $^{9}$He system were investigated by means of the (d,p) reaction. A cryogenic deuterium target was bombarded by a secondary $^{8}$He beam. Complete kinematics measurements were accomplished. The observed $^{9}$He states are broad and overlapping. Their spins and parities have been unambiguously determined. Data from a $^{6}$He($\alpha$,2$\alpha$)2n experiment have been analyzed in terms of a quasi-free scattering approach. A large effect of the 2n final state interaction on the internal $^{6}$He momentum distribution has been demonstrated.
