Constraints on the time-scale of nuclear breakup from thermal hard-photon emission [PDF]
, 2005 Measured hard photon multiplicities from second-chance nucleon-nucleon collisions are used in combination with a kinetic thermal model, to estimate the break-up times of excited nuclear systems produced in nucleus-nucleus reactions at intermediate ...

Synthesis of superheavy nuclei: Obstacles and opportunities
EPJ Web of Conferences, 2015 There are only 3 methods for the production of heavy and superheavy (SH) nuclei, namely, fusion reactions, a sequence of neutron capture and beta(-) decay and multinucleon transfer reactions.

The g-mode spectrum of reactive neutron star cores
, 2019 We discuss the impact of nuclear reactions on the spectrum of gravity g-modes of a mature neutron star, demonstrating the anticipated disappearance of these modes when the timescale associated with the oscillations is longer than that of nuclear ...

Direct mechanism in solar nuclear reactions [PDF]
, 1994 A short overview of the direct reaction mechanism and the models used for the analysis of such processes is given. Nuclear reactions proceeding through the direct mechanism and involved in solar hydrogen burning are discussed.

Nuclear Reactions of Astrophysical Interest
Frontiers in Astronomy and Space Sciences, 2020 We present different reaction models commonly used in nuclear astrophysics, in particular for the nucleosynthesis of the light elements. Nuclear reactions involved in stellar evolution generally occur at energies much lower than the Coulomb barrier. This

Equilibration dynamics in nuclear reactions [PDF]
EPJ Web of Conferences, 2019 We discuss the equilibration dynamics and time–scales for various quantities that are connected to the experimentally observable entities. These include the study of mass, isospin, and total kinetic energy (TKE)equilibration time–scales as well as the ...

The s-Process Nucleosynthesis in Low Mass Stars : Impact of the Uncertainties in the Nuclear Physics Determined by Monte Carlo Variations [PDF]
, 2018 © Springer Nature Switzerland AG 2019We investigated the impact of uncertainties in neutron-capture and weak reactions (on heavy elements) on the s-process nucleosynthesis in low-mass stars using a Monte-Carlo based approach.

The discovery of elements 113 to 118
EPJ Web of Conferences, 2016 Discovery and investigation of the “Island of stability” of superheavy nuclei at the separator DGFRS in the 238U-249Cf+ 48Ca reactions is reviewed. The results are compared with the data obtained in chemistry experiments and at the separators SHIP, BGS ...

Introduction to nuclear astrophysics
, 2009 In the first lecture of this volume, we will present the basic fundamental ideas regarding nuclear processes occurring in stars. We start from stellar observations, will then elaborate on some important quantum-mechanical phenomena governing nuclear ...

Life fingerprints of nuclear reactions in the body of animals [PDF]
, 2010 Nuclear reactions are a very important natural phenomenon in the universe. On the earth, cosmic rays constantly cause nuclear reactions. High energy beams created by medical devices also induce nuclear reactions in the human body.
