The probability distribution of the autocorrelation function of a single particle in a chain of anharmonically coupled oscillators reveals a sharp transition to a phase where ergodicity is 'broken'. The critical value of the control parameter is determined with a precision of 1% by numerical experiments. The phase of 'broken' ergodicity shows up with Poincaré recurrences on observable time scales.
