Excited states of $^{18}$Ne, $^{16}$O, and $^{10}$C in the continuum have been identified using invariant-mass spectroscopy. The best experimental resolution of these states is achieved by selecting events where the decay fragments are emitted transverse to the beam direction. We have confirmed a number of spin assignments made in previous works for the negative-parity states of $^{18}$Ne. In addition we have found new higher-lying excited states in $^{16}$O","authors_text":"A. H. Wuosmaa, D. G. McNeel, D. Weisshaar, J. Manfredi, J. M. Elson, J. Winkelbauer, K. W. Brown, L. G.
