Di - neutron correlation in light neutron - rich nuclei

چکیده

Using a three-body model with density-dependent contact interaction, we discuss the root mean square distance between the two valence neutrons in Li nuclues as a function of the center of mass of the neutrons relative to the core nucleus Li. We show that the mean distance takes a pronounced minimum around the surface of the nucleus, indicating a strong surface di-neutron correlation. We demonstrate that the pairing correlation plays an essential role in this behavior. We also discuss the di-neutron structure in the He nucleus.

The pair correlation is known to play central roles in characterizing various structure aspects of nuclei[ 1]. As far as nuclei near the stability line are concerned, the energy scale of the correlation, the pair gap ∆ ∼ 1 − 2 MeV, is much smaller than the other fundamental energy scales, the Fermi energy eF ∼ 40 MeV, the shell gap ∼ several MeV and the nucleon separation energy ∼ 8 MeV. This s...

Relativistic mean - field study of light nuclei near drip line

The relativistic mean field theory is applied to study some exotic properties of neutron rich nuclei as recently observed, namely, extension of the drip-line for F nuclei from 29 F to 31 F and the appearence of a new shell closure at neutron number N = 16. We find 31 F to be bound against one-neutron dripping but unbound only marginally for two neutron separation. The calculated functional depe...

Nucleon-nucleon momentum correlation function for light nuclei

Nucleon-nucleon momentum correlation function have been presented for nuclear reactions with neutron-rich or proton-rich projectiles using a nuclear transport theory, namely Isospin-Dependent Quantum Molecular Dynamics model. The relationship between the binding energy of projectiles and the strength of proton-neutron correlation function at small relative momentum has been explored, while prot...

The response of Geant4 hadronic models to the study of neutrons produced in proton irradiation to the light materials

Neutron is one of the products of the interaction of high energy protons with light nuclei. Using computational Monte Carlo codes, it is possible to calculate and predict the neutron spectrum, neutron flux, and doses by simulating the system. But the use of different hadronic models in this process can influence the results of these calculations. In this research, the response of the four hadro...
