We investigate the electronic structure of quasi-two-dimensional square quantum dots by using spin-density functional theory. In weak interacting regime, we identify shell fillings due to Hund's rule and calculate electron-number-dependent addition energies dots. To understand interplay between kinetic energy Coulomb examine ground-state spin charge configurations varying size dot. estimate existence Wigner-molecule-like state at a critical mean distance parameter...
Recoiled Compton electrons of 180 deg have been utilized to measure the energy distribution high-intensity bremsstrahlung. An optimized detector-collimator configuration was used for detection and spectrum measurement recoiled electrons. The has reconstructed using cross sections retrieved from ENDF/B.VIII.0 library. measured further validated theoretical simulation by Geant4 code with incorporating ENDF/B-VIII.0–recommended sections. simulated matches if spatial spread electron beam are...
Evaporation residue (ER) cross sections are measured for the reaction $^{30}\mathrm{Si}+^{176}\mathrm{Yb}$, which forms compound nucleus $^{206}\mathrm{Po}^{*}$, over excitation energy range from 47.68 to 113.73 MeV. Dependence of noncompound nuclear on entrance channel parameters such as charge product (${Z}_{1}{Z}_{2}$), mass asymmetry ($\ensuremath{\alpha}$), deformation (${\ensuremath{\beta}}_{2}$) target, and isospin ($\mathrm{\ensuremath{\Delta}}\frac{N}{Z}$) is explored. To analyze...
The capability of standard Geant4 PhysicsLists to address the fragmentation $^{12}$C$-^{12}$C was assessed through a comparative analysis with experimental cross sections reported by Divay et al. and Dudouet were found be inadequate in explaining systematics. To this limitation, breakup component systematically integrated into PhysicsList, which successfully replicated differential double for $\alpha$ production. This modeled using fresco CDCC-CRC calculations. novel physics process then...
The photo nuclear reaction cross section of $^{61}$Ni($\gamma$,xp) have been measured by employing surrogate technique. This indirect method is used for the first time to obtain reaction. compound nucleus $^{61}$Ni$^{*}$ was populated using transfer $^{59}$Co($^{6}$Li,$\alpha$) at E$_{lab}=$ 40.5 MeV. To calculate ratio, $^{60}$Ni($\gamma$,xp) selected as reference and corresponding $^{60}$Ni$^{*}$ $^{56}$Fe($^{6}$Li,d) 35.9 experimental data has taken from EXFOR libraries. Compound...
