Description
The experimental observation of heavy hydrogen resonances allow the study of the most neutron asymmetric matter states in nature.
In my talk I'd like to use the findings in two-neutron + core systems by observing energy and angular correlations iin order to show the prospects when extending the applied methods to the triton + four neutron decay channel of 7H. This extension to the 5 body case would allow for a characterization of the involved continuum structure and to go beyond comparing missing energy spectra to phase space, but will require the detection of four neutrons in coincidence.
The current status and shortcomings for the reliable measurement of many neutrons will be presented and the expected improvements e.g. when being ready to use the currently designed
NeuLAND detector for R³B at GSI and FAIR will be exemplary discussed.
The selective population of the continuum states is another important ingredient for a successful determination of their structure. This will be shown at the example of 13Be* excited states using breakup data, and discussed for the heavy hydrogen systems. The use of kinematical correlations in breakup reactions allows for a further refinement of these selections. Of particular interest is here the quasi-free knockout mechanism where selected examples will be presented.
