The interaction energy among the atoms of liquid helium is not only the usual potential energy, but also we have to consider both the statistical and the quantum effects. The general formulas of their effects have been given by many authors as the expansion ones, in the case of liquid helium however, their convergency is not so good that we can scarcely adopt them to our problem.
In the present paper, we calculate the effective energy from the statistical pair distribution function and show its temperature dependence. Then we investigate that how it must be modified by quantum effect applying it to one example. In the last section we discuss the transition phenomena of He4.
