The completeness of the k orthonormalized eigenstates of the operator \$(a^f(n^)) k(k≥3)\$ is investigated. We introduce an antibunching and a new kind of higher\|order squeezing. The properties of the antibunching effect and M \|th order squeezing of the k states are studied. The result shows that these states may form a complete Hilbert space. There is antibunching effect in all of the states, and the M \|th [M=(n+1/2)k; n=0,1,2,\:] squeezing effects exist in all of the k states when k is even.
