Reinvestigating the Gamow Factor of Reactions on Light Nuclei

The Astrophysical Journal, 2023
We present a modified Gamow factor by reinvestigating the conventional assumptions used in its derivation. The conventional Gamow factor, factorized from the total cross section, effectively describes the penetration probabilities (PPs) in low-energy ...

Description of atomic excitations in heavy-ion reactions [PDF]

, 2006
Excitations of the atomic shell in heavy-ion collisions are influenced by the presence of a nuclear reaction. In the present Rapid Communication we point out the equivalence between a semiclassical description based on the nuclear autocorrelation ...

Unitary correlation in nuclear reaction theory

, 2010
We prove that the amplitudes for the (d,p), (d,pn) and (e,e'p) reactions determining the asymptotic behavior of the exact scattering wave functions in the corresponding channels are invariant under unitary correlation operators while the spectroscopic ...

Delta excitation in K^+-nucleus collisions [PDF]

, 1997
We present calculations for \Delta excitation in the (K^+,K^+) reaction in nuclei. The background from quasielastic K^+ scattering in the \Delta region is also evaluated and shown to be quite small in some kinematical regions, so as to allow for a clean ...

C12+12C fusion S⁎-factor from a full-microscopic nuclear model

Physics Letters B, 2021
The C12+12C fusion reaction plays a vital role in the explosive phenomena of the universe. The resonances in the Gamow window rule its reaction rate and products.

Exploring the nuclear pion dispersion relation through the anomalous coupling of photon to photon and neutral pion

, 1998
We investigate the possibility of measuring the pion dispersion relation in nuclear matter through the anomalous coupling in the reaction \gamma - \gamma' \pi_0. It is shown that this reaction permits the study of pionic modes for space-like momenta.

Determination of plasma screening effects for thermonuclear reactions in laser-generated plasmas

, 2017
Due to screening effects, nuclear reactions in astrophysical plasmas may behave differently than in the laboratory. The possibility to determine the magnitude of these screening effects in colliding laser-generated plasmas is investigated theoretically ...
