The Relevance of Nuclear Reactions for Standard Solar Models Construction

open access: yesFrontiers in Astronomy and Space Sciences, 2021
The fundamental processes by which nuclear energy is generated in the Sun have been known for many years. However, continuous progress in areas such as neutrino experiments, stellar spectroscopy and helioseismic data and techniques requires ever more ...

Spontaneous symmetry-breaking in Elliott-type models and the nuclear deformation

open access: yesPhysics Letters B, 2019
The relation between the spontaneous breaking of the rotational symmetry and the nuclear deformation is discussed in Elliott-type, i.e. algebraic models based on the spherical shell picture.

Consistent assessment of neutron-induced activation of 93Nb

open access: yesFrontiers in Physics, 2023
A concurrent assessment of all measured excitation functions for various reactions induced by neutrons on 93Nb, in addition to the results of TENDL-2021 and default parameters in TALYS-1.96, is given in this work.

Constrained model assumptions using recent data of α-particle reactions on 144Sm

open access: yesFrontiers in Physics, 2023
Analysis of the latest high–precision cross sections of (α,γ) and (α,n) reactions on 144Sm below the Coulomb barrier is carried out using a consistent parameter set of the statistical model.

Potential role of senescent macrophages in radiation-induced pulmonary fibrosis

open access: yesCell Death and Disease, 2021
Radiation-induced pulmonary fibrosis (RIPF) is a late toxicity of therapeutic radiation in clinic with poor prognosis and limited therapeutic options. Previous results have shown that senescent cells, such as fibroblast and type II airway epithelial cell,

Investigating the predicted breathing-mode excitation of the Hoyle state

open access: yesPhysics 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

Nuclear models on a lattice [PDF]

open access: yes, 2005
We present the first results of a quantum field approach to nuclear models obtained by lattice techniques. Renormalization effects for fermion mass and coupling constant in case of scalar and pseudoscalar interaction lagrangian densities are discussed ...

Nuclear Structure Aspects of DCX Reactions and β β Decay Transitions [PDF]

open access: yesEPJ Web of Conferences
The theory of Double Charge Exchange (DCX) reactions between nuclei requires both the description of the reaction mechanism, which consists of the exchange of nucleons between the target and the projectile, as well as the structure of the matrix elements

Nuclear models and the osmium isotopes [PDF]

open access: yes, 1964
The energies of, and transition probabilities involving, the ground-state rotation bands of Os186, Os188, and Os190 are compared with a diagonalized rotation-vibration theory in which vibrations are considered to three phonon order. Agreement even in the
