Beta Decay of Twelve Light Neutron-Rich Isotopes from 17C to 40S
The target fragmentation induced by particule beams is since long recognized as a powerful tool to produce exotic nuclei. Nearly all nuclei with neutron and proton numbers less than that of the target are produced. The drawback of such a wide production is that it implies the use of efficient Z and A selective devices in order to be able to carry detailed spectroscopic measurements. Although very productive, the well-known ISOL facilities do not cover the full range of elements and even in a favorable case like cesium they may fail to separate short-lived isotopes like 113Cs which decays by proton emission. An interesting alternative to ISOL techniques is now available with the fragmentation of heavy ion beams which is essentially equivalent to target fragmentation except for the inverse kinematic. At energies higher than 40Mev/n projectile fragments are forward focused with velocities close to that of the beam.
