Transfer Reactions in Nuclear Astrophysics [PDF]

EPJ Web of Conferences, 2023
Transfer reactions are important tool in nuclear astrophysics. These reactions allow us to identify states in nuclei and to find the corresponding energies, to determine if these states can contribute to astrophysical nuclear reactions and ultimately to ...

Small Effects in Astrophysical Fusion Reactions [PDF]

, 1997
We study the combined effects of vacuum polarization, relativity, Bremsstrahlung, and atomic polarization in nuclear reactions of astrophysical interest.

The Nuclear Reaction Network WinNet

The Astrophysical Journal Supplement Series, 2023
AbstractWe present the state-of-the-art single-zone nuclear reaction networkWinNet, which is capable of calculating the nucleosynthetic yields of a large variety of astrophysical environments and conditions. This ranges from the calculation of the primordial nucleosynthesis, where only a few nuclei are considered, to the ejecta of neutron star mergers ...

Hadrons in the Nuclear Medium [PDF]

, 1998
In this talk I first discuss predictions based on QCD sum rules and on hadronic models for the properties of vector mesons in the nuclear medium. I then describe possible experimental signatures and show detailed predictions for dilepton invariant mass ...

The Competition between 4-Nitrophenol Reduction and BH₄⁻ Hydrolysis on Metal Nanoparticle Catalysts

Molecules, 2023
Assessing competitive environmental catalytic reduction processes via NaBH4 is essential, as BH4− is both an energy carrier (as H2) and a reducing agent. A comprehensive catalytic study of the competition between the borohydride hydrolysis reaction (BHR,

Direct reactions for nuclear astrophysics [PDF]

EPJ Web of Conferences, 2023
The neutron activation technique is a well established method to measure neutron capture cross sections relevant for the s-process. The 7Li(p,n) reaction at Ep = 1912 keV is often used as a neutron source since the energy distribution of the emitted ...

Probing anharmonic properties of nuclear surface vibration by heavy-ion fusion reactions [PDF]

, 1997
Describing fusion reactions between ^{16}O and ^{154}Dy and, between ^{16}O and ^{144}Sm by the $sd-$ and $sdf-$ interacting boson model, we show that heavy-ion fusion reactions are strongly affected by anharmonic properties of nuclear surface vibrations

Raman Study of Polycrystalline Si₃N₄ Irradiated with Swift Heavy Ions

Crystals, 2021
A depth-resolved Raman spectroscopy technique was used to study the residual stress profiles in polycrystalline silicon nitride that was irradiated with Xe (167 MeV, 1 × 1011 cm−2 ÷ 4.87 × 1013 cm−2) and Bi (710 MeV, 1 × 1011 cm−2 ÷ 1 × 1013 cm−2) ions ...

Nuclear reactions in astrophysics

Eurasian Journal of Physics and Functional Materials, 2021
This work is an attempt to present some problems on the evolution of the Universe: the nucleosynthesis and cosmochronology from the standpoint of physics of particles and nuclei, in particular with the use of the lat est results, obtained by means of ...
