Electron-capture rates in the medium-mass nuclei Ti, Ni, Zn, and Ge within deformed quasiparticle random-phase approximation
Eunja Ha, Myung-Ki Cheoun, H. Sagawa +2
Electron-capture (EC) rates in medium-mass nuclei are governed by Gamow--Teller (GT) strength distributions and provide important input for stellar weak-interaction processes. In t…
The Sc, Ti, and V Abundance Discrepancy: Testing High-Mass IMF Variation and Massive-Star Rotation
Soonchul Choi, Eda Gjergo, Youngman Kim +1
Scandium, titanium, and vanadium can be synthesized primarily in massive stars. Yet many of the current Galactic chemical evolution models under-produce these elements at early epo…
High-Precision Measurement of D(, ) Photodisintegration Reaction and Implications for Big-Bang Nucleosynthesis
Yinji Chen, Zirui Hao, Jianjun He +19
We report on a high-precision measurement of the D(,\,) photodisintegration reaction at the newly commissioned Shanghai Laser Electron Gamma Source (SLEGS), employing a q…
Impact of experimental mass of Kr on the Se waiting-point in -process
Min Zhang, Yudong Luo, Akira Dohi +5
The recent mass measurement of Kr using the -defined isochronous mass spectrometry yields a mass excess of keV, indicating a 220-keV increase in binding e…
A Systematic Study of Magnetic Fields Impacts on Neutrino Transport in Core-Collapse Supernovae
Yudong Luo, Shuai Zha, Toshitaka Kajino
We quantify the impact of strong magnetic fields (assuming with G) on the neutrino transport in core-collapse supernovae (CCSNe). Magnet…
High Energy Particle Production from Proton Synchrotron Radiation in Strong Magnetic Fields in Relativistic Quantum Field Theory
Tomoyuki Maruyama, A. Baha Balantekin, Myung-Ki Cheoun +4
We investigate photon, pion, and rho-meson production from proton synchrotron radiation in the presence of strong magnetic fields. The proton decay widths and the luminosities of t…
