چکیده

The production of neutron-rich isotopes and the occurrence neutron capture cascades via laser-driven (pulsed) sources are investigated theoretically. considered scenario involves interaction a beam with target made single type seed nuclide. We present comprehensive study over $95$ nuclides in range $3\le Z \le 100$ from $^7_3$Li to $^{255}_{100}$Fm. For each element, heaviest sufficiently-long-lived (half life $> 1$ h) isotope whose data is available recent ENDF-B-VIII.0 sublibrary considered. identify interesting good performance where may occur. effects number per pulse, neutron-target size pulses also analyzed. Our results show possibility observing up $4$ successive events leading more neutrons than original This hints at new experimental possibilities produce simulate nucleosynthesis laboratory. With several selected region branching point $s$-process ($^{126}_{51}$Sb, $^{176}_{71}$Lu $^{187}_{75}$Re) or waiting $r$-process (Lu, Re, Os, Tm, Ir Au), we expect that experiments can shed light on our understanding nucleosynthesis.

Exploring Neutron-Rich Oxygen Isotopes with MoNA

The Modular Neutron Array (MoNA) was used in conjunction with a large-gap dipole magnet (Sweeper) to measure neutron-unbound states in oxygen isotopes close to the neutron dripline. While no excited states were observed in 24O, a resonance at 45(2) keV above the neutron separation energy was observed in 23O.

Neutron decay spectroscopy of neutron-rich oxygen isotopes

Neutron decay spectroscopy of neutron-rich oxygen isotopes has been performed using the two-proton knock-out reaction 9Be(26Ne,X)24,23,22O. A combination of the knock-out of valence and core protons can explain the three observed spectra. These knock-out processes are selective and preferentially populate hole states. The observed narrow resonance state in 23O at an excitation energy of 2.8(1) ...

One-neutron knockout of very neutron-rich Nitrogen isotopes

The study of exotic nuclei far from the valley of beta stability has attracted in the last decades an enormous interest. Near the neutron dripline the large neutron excess and the low neutron binding energy can lead to dramatic changes in the nuclear structure. This is the case of the so called ”halo nuclei” [1, 2, 3, 4] where low binding energies allow the extension of the wave function of one...

Neutron Shell Breaking in Neutron-Rich Neon Isotopes

The breaking of the N=20 shell gap in neutron-rich nuclei is investigated by studying the single-particle structure of 27Ne via neutron transfer onto a 26Ne beam. The observation of low-lying negative parity states in 27Ne above the 3/2+ ground state is further evidence of the raising of the νd3/2 orbital that is seen in other neutron-rich nuclei in the N=20 region. The previously unseen 7/2− s...

Reaction mechanisms involved in the production of neutron-rich isotopes

The reaction mechanisms best suited for the production of neutron-rich nuclei, fragmentation and fission, are discussed. Measurements of the production cross sections of reaction residues together with model calculations allow to conclude about the expected production rates of neutron-rich isotopes in future facilities.
