Abstract: (Elsevier)

From the 2002 data taking with a neutral kaon beam extracted from the CERN-SPS, the NA48/1 experiment observed 97 @X^0->@S^+@m^-@n@?_@m candidates with a background contamination of 30.8+/-4.2 events. From this sample, the BR(@X^0->@S^+@m^-@n@?_@m) is measured to be (2.17+/-0.32_s_t_a_t+/-0.17_s_y_s_t)x10^-^6.
