Accurate Charge Radius Measurement of C Confronts \textit{Ab Initio} Theory
Kristian König, Patrick Müller, Tobias Gesser +11
Located at the neutron shell closure , the long-lived radioactive isotope \(^{14}\mathrm{C} \) plays a critical role in geochronology and nuclear structure studies. Despite…
Laser spectroscopy illuminates the shell closure
Tim E. Lellinger, Liss V. Rodriguez, Patrick Muller +29
Atomic nuclei are strongly correlated quantum many-body systems, and how their shell structure evolves with increasing neutron excess remains a central open question in nuclear phy…
Two-neutrino double-weak decays of Xe and Xe from different many-body methods
C. Brase, L. Jokiniemi, E. Kauppinen +4
We calculate the nuclear matrix elements and corresponding half-lives for the two-neutrino double-electron capture of Xe and the two-neutrino double-beta decay of X…
Ab initio calculations of two-neutrino and neutrinoless double- decay of Ca and related Gamow-Teller strength distributions
Zhen Li, Lotta Jokiniemi, Achim Schwenk
The paper uses ab initio VS‑IMSRG calculations with chiral EFT interactions to predict two‑neutrino and neutrinoless double‑beta decay rates of ⁴⁸Ca, showing that an enlarged d₃/₂…
r-Process Nucleosynthesis With Ab Initio Nuclear Masses Around The N=82 Shell Closure
Jan Kuske, Takayuki Miyagi, Almudena Arcones +1
Our understanding of the origin of heavy elements beyond iron relies on the rapid neutron capture process (r-process), which accounts for roughly half of their cosmic abundance. Ho…
Ab initio calculations of beta-decay half-lives for neutron-rich nuclei
Zhen Li, Takayuki Miyagi, Achim Schwenk
Beta-decay rates of extreme neutron-rich nuclei remain largely unknown experimentally, while they are critical inputs for -process nucleosynthesis. We present first ab initio ca…
