The objective of the DEAR experiment is a precision measurement of the strong interaction shifts and widths of the K-series lines in kaonic hydrogen and the first observation of the same quantities in kaonic deuterium. These results will allow a precise determination of the isospin dependent kaon-nucleon scattering lengths and will help to determine the kaon-nucleon sigma terms. With the present performance of the DAFNE collider a kaonic hydrogen measurement with a precision better than the best existing experiment seems feasible now. In a preparing experiment kaonic nitrogen X rays were measured.
