摘要: We experimentally detect noise enhanced stability in an unstable physical system. The average escape time from a metastable, periodically driven, system is measured the stable and regimes noisy environment. In regime, we measure that has maximum for finite value of intensity. scaling properties variance times are compared with predictions obtained marginal state.
