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…
