After one year of attending Planck's lectures, Meitner became Planck's assistant. During the first years she worked together with chemist Otto Hahn and together with him discovered several new isotopes. In 1909 she presented two papers on beta radiation. She also, together with Otto Hahn, discovered and developed a physical separation method known as radioactive recoil, in which a daughter nucleus is forcefully ejected from its matrix as it recoils at the moment of decay.
