We present here a new measurement of the p-barp{yields}{pi}{sup 0}{pi}{sup 0} annihilation frequency at rest in liquid hydrogen. The obtained result forms part of a contradictory experimental situation and differs by more than a factor two from the most recent and precise result obtained in the same experimental conditions.
