Structure of nuclei beyond the dripline
نویسنده
چکیده
Fast beams of exotic nuclei produced in fragmentation reactions were used to study nuclei beyond the drip line, where in particular the structure of unbound N = 7 isotopes was explored. An s-wave ground state was established in 10Li and observed for the first time in 9He. A coincidence experiment with γ-rays confirmed that the s-state in 10Li is indeed the ground state. Systematics of proton separation energies can be used to study unbound nuclei beyond the proton dripline.

Particle Unstable Light Nuclei
Exotic nuclei produced in fragmentation reactions can be used to study nuclei beyond the drip lines. The level structure of these nuclei yields information about disappearing, shifting and emerging shells along the driplines. Light nuclei beyond the neutron dripline (for example He, Li, and Be) and the proton dripline (for example N and F) are used to establish the vanishing of the N = 8 and Z ...
متن کاملExplorations along the Neutron Dripline
Reaching the limits of nuclear stability offers unique opportunities to understand basic nuclear properties. Current and future techniques to produce and study very neutron-rich nuclei will be discussed. A few examples of light nuclei which are currently in reach at and even beyond the neutron dripline will be presented.

متن کاملA breakthrough observation for neutron dripline physics
The neutron halo is one of the most spectacular phenomena that nuclear structure physicists have observed in their exploration of the isotopes at and close to the neutron dripline (the curve on a plot of atomic number versus neutron number beyond which neutron-rich nuclei begin “leaking” neutrons) using exotic beam facilities. Atomic nuclei are usually uniformly dense objects with surfaces that...
