    "abstract": "The radial equation of a simple potential model has long been known to yield\nan exponential decay law in lowest order (Breit-Wigner) approximation. We\ndemonstrate that if the calculation is extended to fourth order the decay law\nexhibits the quantum Zeno effect. This model has further been studied\nnumerically to characterize the extra exponential time parameter which\ncompliments the lifetime. We also investigate the inverse Zeno effect.",
