Mass Measurements in Nuclear Reactions

The present status of mass measurements from reactions producing nuclei at the driplines, including those unstable to nucleon or cluster emission, is discussed. The results of recent heavy ion and π-meson induced experiments on the study of the superheavy hydrogen isotopes (⁴H, ⁵H, ⁶H), helium (⁹He, ¹⁰He), lithium (¹⁰Li, ¹¹Li) and beryllium (¹³Be) are given. The possibilities of mass measurements in radioactive ion beam experiments are also considered. This revised version was published online in July 2006 with corrections to the Cover Date.
