We find necessary and sufficient conditions to guarantee the existence resp. coexistence of linear independent periodic zero-elements of period m~, m โ€ข IN, of Hill's differential operator D2 + Q, with co being the minimal period of the function Q. These conditions enable us to construct an unbounded
