Abstract：
Nuclear spectroscopic experiment of nuclei with extreme short half-life far from the β stability by using the RIBLL facility has been carried out.The isotope ²⁹S was produced by projectile fragmentation of 69MeV/u ³⁶Ar ⁺¹⁷on ^natNi with thickness of 92.3mg/cm ². ²⁹S ions were separated and implanted in the Si(Au)detectors.Beta-delayed proton radioactivity has been measured for the ²⁹S isotopes.The measured energy spectrum of β-delayed protons and half-lives are in good agreement with literature.The used experimental method was approved to be feasible for the spectroscopic measurements.
