We study perturbationsĤ of the quantized versionĤ0 of integrable Hamiltonian systems by point interactions. We relate the eigenvalues ofĤ to the zeros of a certain meromorphic function ξ. Assuming the eigenvalues ofĤ0 are Poisson distributed, we get detailed information on the joint distribution of the zeros of ξ and give bounds on the probability density for the spacings of eigenvalues of Ĥ. Our results confirm the “wave chaos” phenomenon, as different from the “quantum chaos” phenomenon predicted by random matrix theory.
