The isotopes 15B, ~sC, 19'2~ 34'35A1 and 39p have been produced as projectile-like fragments from the interaction of a S6Kr beam of 45 MeV/u from GANIL with a lS~Ta target. Separated by the 0 ~ magnetic analyser LISE, the nuclei are identified by means of a AE-E semiconductor telescope. It is surrounded, in a geometry close to 4re, by a thin plastic scintillator (NE 102) and a large volume liquid scintillator (NE 213) for the detection of betas and neutrons, respectively, from the decay of the implanted nuclei.By observation of the/%delayed neutrons, the half-lives T1/2 and neutron emission probabilities P, have been measured. The T1/2 of lsC, ~~ 35A1, 39p and P, of tsC, 19'2~ 34'35A1 and 39p are determined for the first time. For the isotopes 17C, 36'37Si and 38p upper limits of P, are deduced.
