EN

A local pseudopotential in the second-order perturbation theory is used to study the electron dispersion relation, the Fermi energy and deviation in the Fermi energy from free electron value for the liquid alkali metals. The influence of the five different forms of the local field correction functions on the aforesaid electronic properties is examined explicitly, which reflects the varying effects of screening. The depth of the first negative hump in the electron dispersion curves of the liquid alkali metals increases in the order Na, K, Rb, Cs.
