  Abstract
  A microscopic theoretical approach is employed to calculate the detailed dynamical structure factors of an interacting fluid of potassium atoms at its melting temperature. The theoretical investigation is carried out at 338 K, where 0.845 grams of the interacting particles occupy one cubic centimetres of the fluid. The calculations are performed over a range of ? (wave vector): 0.3 Å-1 to 3.0 Å-1. This theoretical approach utilizes the inter-particle interactions present among the constituent particles of the liquid to calculate various dynamical quantities including the dynamical structure factor and the current-current correlation function. The predicted dynamical functions in turn allow for the determination of key transport properties; diffusion coefficient, and longitudinal viscosity and other significant properties, such as collective mode frequencies and the sound velocity. These properties are reported for the entire ?–range. The modified microscopic theory, therefore, is emerged as an inclusive method, for calculating the complete dynamics of liquid potassium at the melting temperature by incorporating inter-particle interactions.
