    We investigate the properties of the focus-beamed magneto-optical trap (FBT) of Rb$^{85}$ atoms, which provides more optical accessibility in contrast to typical magneto-optical trap (MOT). We have characterized the relations between dependent variables i.e. loading time, number and density of trapped atoms versus various trap parameters, e.g. laser intensities, detuning frequency etc. In this...

    Abstract.
    Dynamic viscosity and kinematic viscosity are important physical properties of a liquid. In this work, correlation of dynamic viscosity and kinematic viscosity of fatty acids (FA) are are correlated to the Martin’s rule of free energy additivity for estimated kinematic viscosity and dynamic viscosity from their own equations. The proposed equations for estimating viscosity and...

    Surface tension is important to ensure the efficiency of industrial operation units involving chemical reactions and extractive processes that use these compounds as solvents. In this work, correlation of surface tension of fatty acids (FA) is correlated to the Martin’s rule of free energy additivity for estimated surface tension. The proposed equations for estimating surface tension...

    The non-adiabatic core polarization is used to analyze the measured microwave transitions (B. J. Lyons and T. F. Gallagher, Phys. Rev. A 57, 2426 (1998)) to determine the Mg$^+$ $3s$ dipole and quadrupole polarizabilities. From the calculation, the values of the Mg$^+$ $3s$ dipole and quadrupole polarizabilities are 34.85(23) $a_0^3$ and 78(20) $a_0^5$, respectively.
