12C+12C reactions for Nuclear Astrophysics [PDF]

EPJ Web of Conferences, 2023
12C fusion reactions are among the most important in stellar evolution since they determine the destiny of massive stars. Over the past fifty years, massive efforts have been done to measure these reactions at low energies. However, existing data present

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 ...

Novel QCD Effects from Initial and Final State Interactions [PDF]

, 2007
Initial-state and final-state interactions, which are conventionally neglected in the parton model, have a profound effect in QCD hard-scattering reactions.

Asymptotic normalization coefficient method for two-proton radiative capture

Physics Letters B, 2020
The method of asymptotic normalization coefficients is a standard approach for studies of two-body non-resonant radiative capture processes in nuclear astrophysics.

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 ...

SkyNet: A modular nuclear reaction network library [PDF]

, 2017
Almost all of the elements heavier than hydrogen that are present in our solar system were produced by nuclear burning processes either in the early universe or at some point in the life cycle of stars.

Nuclear Structure and Simple Nuclear Reactions [PDF]

Physical Review, 1960
Recently it has become increasingly evident that some assumptions in the nuclear model used for the Monte Carlo calculations yield cross section values which are not in accord with experiment. In particular, calculations of ($p, \mathrm{pn}$)-reaction cross sections in the Bev energy range give values which are low by factors of two to nine when ...

Peculiarities in the interaction of 6He with 197Au and 206Pb at energies close to the Coulomb barrier [PDF]

Ядерна фізика та енергетика, 2007
Excitation functions for evaporation residues in the reactions 197Au(6He, xn)203-xnTl, where x = 2 - 7, and 206Pb(6He, 2n)210Po, as well as for neutron transfer reactions for the production of 196Au and 198Au in the interaction of 6He with 197Au were ...

The status of new fragment separator ACCULINNA-2 project and the first day experiments

EPJ Web of Conferences, 2014
The new facility fragment separator ACCULINNA-2 will be put into operation at the beginning of 2015 in FLNR JINR. The new separator is destined to add considerably to the studies of drip-line nuclei performed with the use of variety of direct reactions ...

Investigating the predicted breathing-mode excitation of the Hoyle state

Physics Letters B, 2022
Knowledge of the low-lying monopole strength in C12—the Hoyle state in particular—is crucial for our understanding of both the astrophysically important 3α reaction and of α-particle clustering. Multiple theoretical models have predicted a breathing mode
