Abstract
A search for the decay K-S --> pi(0)gammagamma has been made using the NA48 detector at the CERN SPS. Using data collected in 1999 during a 40-hour run with a high-intensity K-S beam, an upper limit for the branching ratio BR(K-S --> pi(0)gammagamma, z greater than or equal to 0.2) < 3.3 x 10(-7) has been obtained at 90% confidence level, where z = m(gammagamma)(2)/m(K0)(2).
