摘要：

The DEAR (DA Phi NE Exotic Atom Research) experiment(1) measured the energy of Xrays emitted in the transitions to the ground states of kaonic hydrogen. The shift E and the width Gamma of the 1s state are sensitive quantities for tests of the current understanding of the low energy antikaon-nucleon interaction. We obtain epsilon(1s) = -193 +/- 37 (stat.) +/- 6 (syst.) and Gamma(1s) = 249 +/- 112 (stat.) +/- 30 (syst.).
