Photon strength functions and nuclear level densities: invaluable input for nucleosynthesis. [PDF]
Philos Trans A Math Phys Eng SciThe pivotal role of nuclear physics in nucleosynthesis processes is being investigated, in particular the intricate influence of photon strength functions (PSFs) and nuclear level densities (NLDs) on shaping the outcomes of the i-, r- and p-processes ...

Unveiling the dynamics of little-bang nucleosynthesis. [PDF]
Nat CommunHigh energy nuclear collisions produce light (anti-)nuclei from the quark-gluon plasma via little-bang nucleosynthesis. Here the authors study the microscopic dynamics of little-bang nucleosynthesis producing deuterons and tritons.

Explosive Nucleosynthesis [PDF]
, 2011 Cosmic nucleosynthesis had been one of INTEGRAL’s major science targets. The SPI spectrometer delivered important measurements, both from targets of opportunity in the form of stellar explosions and their shortlived radionuclides, and from cumulative emission of long-lived radioactive isotopes. We review the lessons learned on explosive nucleosynthesis

Big-bang nucleosynthesis with sub-GeV massive decaying particles [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 We consider the effects of the injections of energetic photon and electron (or positron) on the big-bang nucleosynthesis. We study the photodissociation of light elements in the early Universe paying particular attention to the case that the injection ...

Nucleosynthesis and observation of the heaviest elements [PDF]
European Physical Journal A, 2023 The rapid neutron capture or ‘ r process’ of nucleosynthesis is believed to be responsible for the production of approximately half the natural abundance of heavy elements found on the periodic table above iron (with proton number $$Z=26$$ Z = 26 ) and ...

New models and big bang nucleosynthesis constraints in f(Q) gravity [PDF]
The European Physical Journal C, 2022 The f ( Q ) theories of modified gravity arise from the consideration of non-metricity as the basic geometric quantity, and have been proven to be very efficient in describing the late-time Universe.

Neutrino decoupling including flavour oscillations and primordial nucleosynthesis [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 We revisit the decoupling of neutrinos in the early universe with flavour oscillations. We rederive the quantum kinetic equations which determine the neutrino evolution based on a BBGKY-like hierarchy, and include for the first time the full collision ...
