Let M be a left R-module. X,Y of M are β* equivalent, Xβ*Y, if and only if (Formula Presented) is small in (Formula Presented) and (Formula Presented) A module M is called G*-supplemented if for every submodule X of M there is a supplement submodule S of M such that Xβ*S. In this work some new properties of β* are given and G*-supplemented modules are studied. Also completely G*-supplemented modules and G*-radical supplemented modules are defined.
