    "abstract": "We analyze the experimental observations reported by Fischer et. al. [in\nPhys. Rev. Lett. 87, 040402 (2001)] by considering a system of coupled unstable\nbound quantum states A and B. The state B is coupled to a set of continuum\nstates C. We investigate the time evolution of A when it decays into C via B,\nand find that frequent measurements on A leads to both the quantum Zeno effect\nand the anti-Zeno effects depending on the frequency of measurements. We show\nthat it is the presence of B which allows for the anti-Zeno effect.",
