Some lessons from invariant mass spectroscopy about light nuclei

International audienceOver the past decade, secondary-beam experiments utilizing the invariant mass technique have generated a wealth of data on light nuclei. This includes: discovery of new isotopes, finding previously unknown states and refining the properties of known states (some as astrophysical significance), finding new (and some unusual) cases of 2p decay, and dynamical study of reaction and 3-body decay mechanisms. This talk will fous on two recently found resonances that are ushered to the just above the proton threshold, and imprinted with large proton spectroscopic factors, by the continuum coupling to open neutron (as well as proton) channels. The insight into the symbiotic impact multiple continua play was enabled by a continuum cognizant shell model for which both proton and neutron continua are coherently considered. Because of the nature of this meeting we also present preliminary data on the fission of 16O fission into two 8Be nuclei. We begin by presenting an outline of the means by which such data are collected
