The DEAR (DAΦNE exotic atom research) experiment measured the energy of x rays emitted in the transitions to the ground state of kaonic hydrogen. The measured values for the shift ε and the width Γ of the 1<i>s</i> state due to the <i>K</i>⁻<i>p</i> strong interaction are ε<sub>1<i>s</i></sub>=-193±37 (stat) ±6 (syst) eV and Γ<sub>1<i>s</i></sub>=249±111 (stat) ±30 (syst) eV, the most precise values yet obtained. The pattern of the kaonic hydrogen <i>K</i>-series lines, <i>K</i><sub>α</sub>, <i>K</i><sub>β</sub>, and <i>K</i><sub>γ</sub>, was disentangled for the first time.
