Monday Parallel Session: Few-body systems and astrophysics (Linke Aula)

Thermonuclear reactions involving charged particles play a central role in stellar evolution. Knowledge of their rates is needed to answer fundamental questions about the origin of the elements. While direct measurement approaches are a powerful tool to study nuclear cross-section, the hindering effect of the Coulomb barrier makes measurement at energies of stellar interest extremely...
We present a theoretical study of the $^{6}$Li + p $\to$ $^{3}$He + $\alpha$ direct transfer reaction at collision energies from few keV to around the Coulomb barrier ($\sim$ 1.5 MeV in the center of mass). This lithium-depleting process is of interest from the astrophysical point of view [1.
Radiative capture reactions with light neutron-rich nuclei are known to be important constituents at sites of explosive nucleosynthesis while producing seed nuclei for the $r$-process. One such important reaction is the $^{11}$B(n,$\gamma$)$^{12}$B radiative neutron capture reaction, where the total reaction rate has significant contributions from the resonant (narrow-resonances) as well as...
We investigated the radiative proton capture on nitrogen isotopes $^{12}$N, $^{13}$N, and $^{14}$N [1 - 4] in the framework of the MPCM and obtained the reaction rates and their parametrizations. There are two stable nitrogen isotopes $^{14}$N and $^{15}$N, and among short-lived nitrogen isotopes, the longest-lived are $^{12}$N ($t_{1/2} = 11$ ms) and $^{13}$N ($t_{1/2} = 9.965$ min).

A trion is the bound state of an exciton with another charged carrier, which can either be an electron (X⁻ trion) or a hole (X⁺ trion). We develop the theoretical formalism and study the formation of valleytrions in transition metal dichalcogenides monolayers within the framework of a nonrelativistic potential model using the method of hyperspherical harmonics (HH) in four-dimensional space....
