Quasi-elastic scattering with central dipion cluster production is studied in π+p and K+p interactions at 250 GeV/c. The cross section of double pomeron exchange is obtained as σDPE(π+p →π+(π+π-)p)=24 ±5 μb and σDPE(K+p→K+(π+π-)p)=19 ±5 μb. The low energy pomeron-pomeron cross section is estimated for the first time.
