  author={Le Hoang Anh Nguyen and Minh-Loc Bui and Naftali Auerbach and Vladimir Zelevinsky},
The excitation function of proton elastic scattering from 10 Be at keV energy is calculated using the self-consistent Skyrme Hartree-Fock in the continuum method. The calculation successfully reproduces the narrow near-threshold proton-emitting resonance ( E x = 11 . 4 MeV, Γ = 6 keV, and quantum number J π = 1 / 2 + ) in 11 B relevant to the β -delayed proton emission of 11 Be. This supports the recent experimental result of Y. Ayyad et al. at the ReA3 re-accelerator facility of the National…

New Skyrme interaction with improved spin-isospin properties

A correct determination of the spin-isospin properties of the nuclear effective interaction should lead to, among other improvements, an accurate description of the Gamow-Teller resonance (GTR).

Bound-to-continuum potential model for the $(p,\gamma)$ reactions of the CNO cycle

The study of CNO cycle involves the examination of the proton radiative capture, or the (p, γ) reactions below 2 MeV. The astrophysical S factor characterizing the (p, γ) reaction is usually reduced

Assessment of the beta-delayed proton decay rate of 11Be

The 11Be neutron halo nucleus appears to decay into 10Be with a rate that exceeds expectations. Neutron disappearance into dark matter, beta decay of a halo neutron, or beta-delayed proton decay have

Search for beta-delayed proton emission from $$^{11}$$Be

We report on an attempt to reproduce the observation of $\beta^-$-delayed proton emission from $^{11}$Be through detection of the final state nucleus $^{10}$Be with accelerator mass spectrometry.

Convenient Location of a Near-Threshold Proton-Emitting Resonance in ^{11}B.

The structure of the recently observed near-threshold resonance in ^{11}B, whose very existence explains the puzzling beta-delayed proton emission of the neutron-rich ^{ 11}Be, is discussed.
