Production and identification of new nuclei at the neutron and proton drip‐lines for light isotopes

By combining the effectiveness of the projectile‐fragmentation mechanism at intermediate energy, the relatively high beam intensities available at GANIL and the performances of the doubly achromatic spectrometer LISE, a breakthrough has been achieved in reaching the neutron and proton drip‐lines. The achromatic refocusing of the products by the spectrometer allows identification by a small high‐resolution solid‐state detector telescope. Combined with the time of flight measurement of the nuclei, a redundant determination of A and Z is ensured. By fragmentation of various profectiles such as 40Ar, 36Ar, 86Kr, 40Ca, 58Ni, it has been possible to produce new light neutron‐ rich or neutron‐deficient nuclei.
