Role of correlations in spin-polarized neutron matter

Author(s): Isaac Vidaña, Artur Polls, and Victoria Durant

This paper uses Brueckner theory in its accepted modern form to definitively establish that neutron matter, in the density regime relevant to neutron stars, does not suffer any ferromagnetic instability. This result shows that a ferromagnetic transition cannot be the origin of the magnetic fields in neutron stars.

Applicability of the continuum-discretized coupled-channels method to the deuteron breakup at low energies

Author(s): Kazuyuki Ogata and Kazuki Yoshida

The authors present break-up reaction calculations, which are important but difficult. Their calculations show that the continuum discretized coupled channels (CDCC) method provides reliable results for break-up reactions, in contrast to a recent publication claiming strong discrepancies with Faddeev results, provided that closed channels are included. Thus, the CDCC method can be reliably used rather than the more difficult three-body approach.

Direct measurement of low-energy ^{22} Ne(p,γ) ^{23} Na resonances

2016-11-21T10:00:00-05:00

Author(s): R. Depalo et al. (LUNA Collaboration)

The authors perform a direct measurement of radiative proton capture on ${}^{22}$Ne at the LUNA underground laboratory whose low background allows unprecedented sensitivity. They report detailed experimental information for three recently observed new resonances in the ${}^{22}$Ne($p$,$\gamma$)${}^{23}$Na reaction which is the most uncertain process in the neon-sodium cycle of stellar hydrogen burning. At temperatures relevant for nucleosynthesis in asymptotic giant branch stars and classical novae, its uncertainty is mainly due to a large number of predicted but hitherto unobserved resonances at low energy. The updated thermonuclear reaction rate is significantly higher than previous evaluations at temperatures below 0.3 GK.

The ^{30} Mg(t,p) ^{32} Mg “puzzle” reexamined

2016-11-18T10:00:00-05:00

The nucleus ${}^{32}$Mg sits within the so-called island of inversion. In simplest terms, the ${}^{32}$Mg ground state (nominally a closed neutron, $N=20$, shell) is dominated by components involving neutrons excited to the next higher, $p\phantom{\rule{0}{0ex}}f$ shell. Extended shell-model calculations show that particle-hole states (0p0h, 2p2h, and 4p4h) are important. The present work demonstrates that ${}^{30}$Mg($t$,$p$)${}^{32}$Mg two-neutron transfer cross sections to the first two ${0}^{+}$ states can be understood in a simple three-state mixing model.

Rearrangement of valence neutrons in the neutrinoless double-β decay of ^{136} Xe

Author(s): S. V. Szwec, B. P. Kay, T. E. Cocolios, J. P. Entwisle, S. J. Freeman, L. P. Gaffney, V. Guimarães, F. Hammache, P. P. McKee, E. Parr, C. Portail, J. P. Schiffer, N. de Séréville, D. K. Sharp, J. F. Smith, and I. Stefan

In neutrinoless double-$\beta$ decay such as ${}^{136}$Xe to ${}^{136}$Ba, two neutrons become two protons, thus rearranging the occupancy of protons and neutrons in the ground states of the parent and daughter nuclei. From precision measurements of the cross sections of single-neutron adding and -removing reactions, the authors extract the change in ground-state neutron occupancies between ${}^{136}$Xe and ${}^{136}$Ba. Along with recent results on the proton occupancies, the new experimental neutron occupancies disagree with those used in existing theoretical calculations of the rate of this elusive $\beta$-decay mode, and provide a ​ ​basis for improved estimates of the uncertainties for new calculations.

Hadronic weak charges and parity-violating forward Compton scattering

2016-11-14T10:00:00-05:00

Author(s): Mikhail Gorchtein and Hubert Spiesberger

The authors consider contributions to parity-violating electron-proton scattering from two-photon exchange, where the electromagnetic interaction of the nucleon has a parity-violating component. Unlike the standard short-ranged weak interaction conveyed by a massive $Z$ boson, the considered mechanism induces novel long-range parity-violating forces. This is relevant for upcoming measurements at electron accelerator facilities at the University of Mainz and Jefferson Laboratory, including the Q-Weak experiment. The results will allow access to the weak charge of the nucleon and thereby, potentially, to physics beyond the Standard Model.

After identifying the nuclei in the A≃80 and A≃160 regions for which β-decay rates have the greatest effect on weak and main r-process abundance patterns, we apply the finite-amplitude method (FAM) with Skyrme energy-density functionals (EDFs) to calculate β-decay half-lives of those nuclei in the q…

Single-particle and collective motion in unbound deformed ^{39} Mg

2016-11-04T10:00:00-04:00

Author(s): K. Fossez, J. Rotureau, N. Michel, Quan Liu (刘泉), and W. Nazarewicz
Background: Deformed neutron-rich magnesium isotopes constitute a fascinating territory where the interplay between collective rotation and single-particle motion is strongly affected by the neutron continuum. The unbound fp-shell nucleus ^{39}Mg is an ideal candidate to study this interplay.
