An electric sum rule for photonnuclear and electron-scattering transitions, valid for all multipolarities greater than the monopole (L = 0) case, is derived. This sum rule, which includes both current and magnetization-induced transitions, is developed in the long-wavelength limit for isovector ΔT = 1 transitions. It is used to analyze nuclear charge–matter distributions for high multipolarity transitions in light nuclei.

Spin Flip

We have derived a spin flip magnetic multipole sum rule for magnetic dipole (ML) transitions, L ≥ 2 of T = 1 type, valid in the long-wavelength limit. It is applied to known ML transitions in several light nuclei, including recently measured M6 and M8 transitions in inelastic electron scattering, and the degree of sum-rule exhaustion is determined.

Thermodynamic properties, such as free energy of mixing, heat of mixing, entropy of mixing, activities and the microscopic structural properties, such as concentration fluctuation in long-wavelength limit and chemical short-range order parameter of Pb-Tl liquid alloy at 773 K have been studied on the basis of regular associated solution model. We have estimated the mole fractions of the complex and the unassociated atoms assuming the existence of  complex as energetically favoured in the liquid state. The compositional contributions of the heat of mixing of the species Pb and Tl and the heat of formation of the compound to the net enthalpy change have also been studied. The transport properties such as, viscosity and the ratio of mutual and intrinsic coefficients have been studied using different approaches. The surface concentration of Tl atoms has been computed and it has been employed to calculate the surface tension of Pb-Tl liquid alloy. Both the theoretical and the experimental values of the concentration fluctuation in long-wavelength limit are found to be less than the ideal value, revealing that the concerned system is hetero-coordinating in nature. The interaction energies are found to be temperature dependent and respective alloy is found to be weakly interacting system. BIBECHANA 13 (2016) 100-113
