Neutron captures in stellar nucleosynthesis [PDF]
EPJ Web of Conferences, 2023 Apart from cosmological hydrogen and helium, chemical elements in the Universe are produced in stars, during both quiescent and explosive phases. The Sun chemical distribution witnesses the pollution from already extinct stellar generations at different ...

Experiments probing clustering effects in explosive nucleosynthesis
Frontiers in Physics, 2023 Nuclear clustering affects the nucleosynthesis occurring in a number of astrophysical environments. Highly-clusterized nuclear states typically occur near particle thresholds and therefore can produce dramatic impacts on the nuclear reaction rates.

Explosive Nucleosynthesis Study Using Laser Driven γ-ray Pulses
Quantum Beam Science, 2017 We propose nuclear experiments using γ-ray pulses provided from high field plasma generated by high peak power laser. These γ-ray pulses have the excellent features of extremely short pulse, high intensity, and continuous energy distribution.

Isotope relations of transuraniums under conditions of the artificial explosive nucleosynthesis
Results in PhysicsArtificial creation of isotopes under extremal neutron fluxes at nuclear explosions allowed to obtain the identifiable quantities of transuraniums with neutron excess up to 19. The analysis of yield relations between produced neighboring isotopes (with A-

Ar+ ArH+ Reactive Collisions of Astrophysical Interest: The Case of 36Ar
ChemPhysChem, Volume 24, Issue 20, October 17, 2023., 2023 A complete theoretical investigation of the 36Ar+36ArH+ reactive collision involving the most abundant Argon isotope in the interstellar medium. Abstract The reactive collision between 36Ar and the 36ArH+ species has been investigated by means of quantum mechanical (QM), quasiclassical trajectories (QCT) and statistical quantum mechanical (SQM ...

Geophysical Research Letters, Volume 50, Issue 4, 28 February 2023., 2023 Abstract We employed MC‐ICP‐MS to measure the mass‐dependent Ca isotope compositions of Vesta‐related meteorites. Eucrites and diogenites show distinct Ca isotope compositions, which is caused by crystallization of isotopically heavy orthopyroxene. The Ca isotope data support a model where the two lithologies are linked, where the diogenites, mainly ...

Possible Control of Earth's Boron Budget by Metallic Iron
Geophysical Research Letters, Volume 49, Issue 10, 28 May 2022., 2022 Abstract Boron is considered a principal tracer for crustal recycling into the depleted mantle, and high boron anomalies and isotopically light boron (10B) in mantle‐derived samples have been interpreted as the result of subduction. Using density functional theory, we predict that boron behavior changes from lithophile to siderophile, with the ...

Expanding Nuclear Physics Horizons with the Gamma Factory
Annalen der Physik, Volume 534, Issue 3, March 2022., 2022 The Gamma Factory is an ambitious proposal for a source of photons with energies up to hundreds of MeV and photon fluxes exceeding those of the currently available gamma sources by orders of magnitude. The paper surveys the new opportunities in nuclear physics and related fields that may be afforded by the this facility. Abstract The Gamma Factory (GF)

Laboratory exploration of mineral precipitates from Europa's subsurface ocean
Journal of Applied Crystallography, Volume 54, Issue 5, Page 1455-1479, October 2021., 2021 Precipitation experiments from a model Europan ocean solution subjected to fast and slow freezing suggest that the highly hydrated Na–Mg sulfate phase Na2Mg(SO4)2·16H2O is one of the lowest‐temperature mineral phases likely to be stable on Europa's surface and may therefore be astrobiologically significant.The precipitation of hydrated phases from a ...

Sensitivity of He Flames in X-Ray Bursts to Nuclear Physics
The Astrophysical Journal, 2023 Through the use of axisymmetric 2D hydrodynamic simulations, we further investigate laterally propagating flames in X-ray bursts (XRBs). Our aim is to understand the sensitivity of a propagating helium flame to different nuclear physics. Using the Castro
