Low-lying dipole strength in neutron-rich nuclei
The possibility of performing nowadays reactions with beams of unstable nuclei has opened a new field of study in nuclear physics. Using stable nuclei as targets and carrying out the experiments in inverse kinematics it becomes possible to have access to the excitation spectrum of the incoming short-lived projectiles. To this aim the most often used reactions are the Coulomb excitation and the ...
متن کاملElectromagnetic strength of neutron and proton single-particle halo nuclei
Electromagnetic strength functions of halo nuclei exhibit universal features that can be described in terms of characteristic scale parameters. For a nucleus with nucleon+core structure the reduced transition probability, as determined, e.g., by Coulomb dissociation experiments, shows a typical shape that depends on the nucleon separation energy and the orbital angular momenta in the initial an...
متن کاملDistribution of partial neutron widths for nuclei close to a maximum of the neutron strength function.
For nuclei near a maximum of the neutron strength function, the secular dependence on energy E of s-wave partial neutron widths differs from the canonical form √E. We derive the universal form of that dependence and show that it is expected to significantly influence the analysis of neutron resonance data.
متن کاملNeutron–proton Pairs in Nuclei
A review is given of attempts to describe nuclear properties in terms of neutron–proton pairs that are subsequently replaced by bosons. Some of the standard approaches with low-spin pairs are recalled but the emphasis is on a recently proposed framework with pairs of neutrons and protons with aligned angular momentum. The analysis is carried out for general j and applied to N = Z nuclei in the ...
متن کاملNeutron scattering on nuclei.
Very small angle neutron scattering studies have been made on intact nuclei under a variety of solution conditions. Scattering maxima are observed at 30 to 40 nm and at 18 nm in most environments. Although the spacing, intensity and presence of the maximum near 40 nm varies considerably with environment the 18 nm is rather constant. The 30 to 40 nm maximum appears to be best interpreted by the ...
