Let G be a p-solvable finite group for some prime p, \(G_{p'}\) a \(p'\)-Hall subgroup of G and x a p-regular element of G. Clearly, \(\langle x\rangle \le C_G(x)\le G\). Notice that the structure of \(G_{p'}\) is easily decided when \(C_G(x)=\langle x\rangle \) and \(C_G(x)=G\) for every p-regular element x of G. So, in this paper, we investigate the structure of \(G_{p'}\) by assuming that \(C_G(x)\) is maximal in G for every non-central p-regular element x of G.
