The Effects of Thermonuclear Reaction-Rate Variations on 26Al Production in Massive Stars: a Sensitivity Study [PDF]

, 2011
We investigate the effects of thermonuclear reaction rate variations on 26Al production in massive stars. The dominant production sites in such events were recently investigated by using stellar model calculations: explosive neon-carbon burning ...

Challenges and Requirements in High-Precision Nuclear Astrophysics Experiments

Universe, 2022
In the 21th century astronomical observations, as well as astrophysical models, have become impressively precise. For a better understanding of the processes in stellar interiors, the nuclear physics of astrophysical relevance—known as nuclear ...

Benchmarking GEANT4 nuclear models for hadron therapy with 95 MeV/nucleon carbon ions [PDF]

, 2014
In carbon-therapy, the interaction of the incoming beam with human tissues may lead to the production of a large amount of nuclear fragments and secondary light particles.

Rearrangement Nuclear Reactions and Optical Model [PDF]

Progress of Theoretical Physics, 1962
The formula for rearrangement nuclear reactions which describe both direct and compound processes from a unified point of view is derived in a manner simular to that for nucleon scattering by nuclei. The distortion of wave functions for a particle concerned in the rearrangemest reaction is given by the optical potential determined from the elastic ...

Nuclear uncertainties in the NeNa-MgAl cycles and production of 22Na and 26Al during nova outbursts [PDF]

, 1999
Classical novae eject significant amounts of nuclear processed material into the interstellar medium. Among the isotopes synthesized during such explosions, two radioactive nuclei deserve a particular attention: 22Na and 26Al.

Measurement of (n, xnγ) reaction cross sections in W isotopes

EPJ Web of Conferences, 2017
Evaluated nuclear data bases currently used for numerical simulation for the development of nuclear reactors still present large uncertainties. Their improvement is necessary, in particular through better reaction models and nuclear data.

Study of (n,2n) reaction cross section of fission product based on neural network and decision tree models [PDF]

EPJ Web of Conferences
The neutron induced nuclear reaction cross sections of fission products are related with the neutron fiux and the reactor burnup, which are important for the accurate of nuclear engineering design. To predict the (n,2n) reaction cross section, especially

Flow probe of symmetry energy in relativistic heavy-ion reactions [PDF]

, 2013
Flow observables in heavy-ion reactions at incident energies up to about 1 GeV per nucleon have been shown to be very useful for investigating the reaction dynamics and for determining the parameters of reaction models based on transport theory.

A new route to produce 52gMn with high purity for MultiModal Imaging [PDF]

EPJ Web of Conferences, 2022
The 52gMn radionuclide is suitable for the innovative MultiModal Imaging technique, and in particular for a PET/MRI scan, due to its physical properties. The standard cyclotron-based production of 52gMn relies on the nuclear reaction NatCr(p,x)52gMn, but

Reaction Rate Uncertainties: NeNa and MgAl in AGB Stars [PDF]

, 2006
We study the effect of uncertainties in the proton-capture reaction rates of the NeNa and MgAl chains on nucleosynthesis due to the operation of hot bottom burning (HBB) in intermediate-mass asymptotic giant branch (AGB) stars.
