Corsi, A., Kubota, Y., Authelet, G. et al. (60 more authors) (2026) Observation of a broad $p$-wave resonant state in $^{9}$He. [Preprint]
Abstract
We report on the two-body invariant-mass spectroscopy of $^{9}$He, populated via the 1$p$1$n$ knockout reaction from the two-neutron halo nucleus $^{11}$Li at $\sim$250 MeV/nucleon. A broad $p$-wave resonant state of $^{9}$He was observed at 1.28(1) MeV with a width of 0.82(4) MeV.
