AbstractAbstract
[en] Neutron-rich isotopes have been produced by the fragmentation of 55 MeV/nucleon 48Ca projectiles from GANIL into a 181Ta target. The nuclei were separated by means of the doubly achromatic spectrometer LISE and implanted into a semiconductor telescope for identification in Z and A. Their β-delayed neutron radioactivity is observed by means of a 4π β-neutron coincidence detector. The rsults include first measurements of the half-life T1/2 and the neutron emission probability Pn for the isotopes 20C, 40,41,42P and 43,44S. They are compared with theoretical predictions. 15 refs.; 2 figs.; 2 tabs
