Author(s): Xiao-Dong Sun, Chao Duan, Jun-Gang Deng, Ping Guo, and Xiao-Hua Li
α decay is usually associated with both ground and low-lying isomeric states of heavy and superheavy nuclei, and the unpaired nucleon plays a key role in α decay. In this work, we systematically studied the α decay half-lives of odd-A nuclei, including both favored and unfavored α decay within the t…

We develop a multidimensionally constrained relativistic Hartree-Bogoliubov (MDC-RHB) model in which the pairing correlations are taken into account by making the Bogoliubov transformation. In this model, the nuclear shape is assumed to be invariant under the reversion of x and y axes; i.e., the int…

In this article we extend previous work on efficiency corrections for cumulant measurements [Bzdak and Koch, Phys. Rev. C 86, 044904 (2012); Phys. Rev. C 91, 027901 (2015)]. We will discuss the limitations of the methods presented in these papers. Specifically we will consider multiplicity dependent…

Partial-wave analysis of nucleon-nucleon elastic scattering data

2016-12-19T10:00:00-05:00

Author(s): Ron L. Workman, William J. Briscoe, and Igor I. Strakovsky
Energy-dependent and single-energy fits to the existing nucleon-nucleon database have been updated to incorporate recent measurements. The fits cover a region from threshold to 3 GeV, in the laboratory kinetic energy, for proton-proton scattering, with an upper limit of 1.3 GeV for neutron-proton sc…

The ^{23}Na(α,p)^{26}Mg and ^{23}Na(α,n)^{26}Al reactions are important for our understanding of the ^{26}Al abundance in massive stars. The aim of this work is to report on a direct and simultaneous measurement of these astrophysically important reactions using an active target system. The reaction…

Υ production in U + U collisions at sqrt[s_{NN} ] =193 GeV measured with the STAR experiment

2016-12-15T10:00:00-05:00

Author(s): L. Adamczyk et al. (STAR Collaboration)
We present a measurement of the inclusive production of Υ mesons in U+U collisions at sqrt[s_{NN}]=193 GeV at midrapidity (|y|<1). Previous studies in central Au+Au collisions at sqrt[s_{NN}]=200 GeV show a suppression of Υ(1S+2S+3S) production relative to expectations from the Υ yield in p+p collisions scaled by the number of binary nucleon-nucleon collisions (N_{coll}), with an indication that the Υ(1S) state is also suppressed. The present measurement extends the number of participant nucleons in the collision (N_{part}) by 20% compared to Au+Au collisions, and allows us to study a system with higher energy density. We observe a suppression in both the Υ(1S+2S+3S) and Υ(1S) yields in central U+U data, which consolidates and extends the previously observed suppression trend in Au+Au collisions.

Measurement of radiative proton capture on ^{18} F and implications for oxygen-neon novae reexamined

Background: The rate of the ^{18}F(p,γ)^{19}Ne reaction affects the final abundance of the radioisotope ^{18}F ejected from novae. This nucleus is important as its abundance is thought to significantly influence the first-stage 511-keV and continuum γ-ray emission in the aftermath of novae. No succe…

Empirical parametrization of the nucleon-nucleon elastic scattering amplitude at high beam momenta for Glauber calculations and Monte Carlo simulations

Author(s): V. Uzhinsky, A. Galoyan, Q. Hu, J. Ritman, and H. Xu
A parametrization of the nucleon-nucleon elastic scattering amplitude is needed for future experiments with nucleon and nuclear beams in the beam momentum range of 2–50 GeV/c/nucleon. There are many parametrizations of the amplitude at P_{lab}> 25–50 GeV/c, and at P_{lab}≤5 GeV/c. Our paper is aimed …

New levels and γ-ray transitions were identified in ^{150,152}Sm utilizing the (p,t) reaction and particle-γ coincidence data. A large, peak-like structure observed between 2.3–3.0 MeV in excitation energy in the triton energy spectra was also investigated. The orbital angular-momentum transfer was …

γ rays following the EC/β^{+} and α decay of the N = 126, ^{213}Fr nucleus have been observed at the CERN isotope separator on-line (ISOLDE) facility with the help of γ-ray and conversion-electron spectroscopy. These γ rays establish several hitherto unknown excited states in ^{213}Rn. Also, five ne…
