This work calculates the Lorentz–Lorenz coefficient with refractive index and density values of various molecules in their solid phase measured our laboratory under astrophysical conditions. was completed for a range temperatures from 13 K to close sublimation temperature each molecule. The studied were N2, CO2, NH3, CH4, CH3OH, C2H4, C2H6. For results match those found unique similar previous ...

In this article, we study the mass spectra of baryons containing two heavy quarks; charm-charm ($cc$) and bottom-charm ($bc$) with a light quark ($u,d,s$) within framework Regge phenomenology. With assumption linear trajectories have derived relations between slope ratios, intercepts, baryon masses. Using these relations, ground state masses $\Xi_{cc}$, $\Xi_{bc}$, $\Omega_{cc}$, $\Omega_{bc}$ ...

Abstract Herein, we present a detailed study of the structural, optical, and electrochemical responses Gd 2 O 3 doped with nickel zinc ferrite nanoparticles. Doping Ni 0.5 Zn Fe 4 nanoparticles to powder was done through thermal decomposition at 1000 °C. The average grain size mixture determined be approximately 95 nm, phases cubic , GdO, orthorhombic prisms GdFeO were identified. focused ion b...
