Neutron Capture and Neutron Halos
The connection between the neutron halo observed in light neutron rich nuclei and the neutron radiative capture process is outlined. We show how nuclear structure information such as spectroscopic factors and external components of the radial wave function of loosely bound states can be derived from the neutron capture cross section. The link between the direct radiative capture and the Coulomb...
متن کاملExcited state halos in 10 Be
The structure of certain bound excited states in 10Be have been shown to have exotic features because of their weak binding and cluster-like configurations. In this article, we investigate E1 and E2 transitions between these states and compare the findings with recent experimental results. We compare the predictions of two types of structure calculations: a microscopic multicluster model and an...
متن کامل5 Unexpected neutron structure effects in one neutron halos
Although the neutron (n) does not carry a total electric charge, its charge distribution represented in momentum space by the first electromagnetic form factor, F (n) 1 (q 2), leads to a spin independent electric potential. We calculate the first order electromagnetic corrections to the binding energy of a one neutron halo nucleus by evaluating the potential between the neutron and the charged ...
متن کاملNeutron halos in the Na isotopes.
The neutron and proton density distributions of the Na isotopes out to the proton and neutron drip lines are calculated in the spherical Hartree-Fock model with a wide variety of density-dependent Skyrme interactions. The results are compared to recent experimental data for the interaction cross sections and for the rms radii. We discuss the role of the deformed intruder states and the problems...
متن کاملPolarizability in Excited States
A linear response of a molecule in excited state to an external electric field is discussed in terms of frequency dependent polarizabilities. Results of accurate calculations of polarizabilities of the hydrogen molecule in its b aL: and B lL/ states are presented. The results are compared with other ab initio and model calculations. It is shown that there is no contribution to the polarizabilit...
