Large Acceptance Spectrometers for Invariant Mass Spectroscopy of Exotic Nuclei and Future Developments
Large acceptance spectrometers at in-flight RI separators have played significant roles in investigating the structure of exotic nuclei. Such spectrometers are in particular useful for probing unbound states of exotic nuclei, using invariant mass spectroscopy with reactions at intermediate and high energies. We discuss here the key characteristic features of such spectrometers, by introducing t...
متن کاملFirst Penning-trap mass measurement of the exotic halo nucleus 11Li.
In this Letter, we report a new mass for 11Li using the trapping experiment TITAN at TRIUMF's ISAC facility. This is by far the shortest-lived nuclide, t_{1/2}=8.8 ms, for which a mass measurement has ever been performed with a Penning trap. Combined with our mass measurements of ;{8,9}Li we derive a new two-neutron separation energy of 369.15(65) keV: a factor of 7 more precise than the best p...

The neutron–9Li interaction and the corresponding low-energy 10Li spectrum are decisive for the properties of 11Li described as a three-body system (n+n+9Li). We compute structure and breakup properties of 11Li as function of this interaction. The hyperfine structure due to the spin 3/2 of both 9Li and 11Li is needed and treated with special care. We use the hyperspherical adiabatic expansion o...
متن کاملIs mass conformally invariant ?
By using the Garfinkle, Horowitz and Strominger black hole solutions as examples, we illustrate that, with respect to the reference action functional proposed by Hawking and Horowitz, the asymp-totic mass parameter is not invariant between two conformally related static spherically symmetric metrics.
متن کاملMomentum distributions of particles from three-body halo fragmentation: Final state interactions.
Momentum distributions of particles from nuclear break-up of fast threebody halos are calculated consistently, and applied to 11Li. The same twobody interactions between the three particles are used to calculate the ground state structure and the final state of the reaction processes. We reproduce the available momentum distributions from 11Li fragmentation, together with the size and energy of...
