Abstract：
The β-‘waiting point’nucleus ⁹³Pd has been produced via ⁵⁸Ni(⁴⁰Ca,3n2p) reaction. A helium-jet fast tape transport system was used in combination with p-γ coincidence measurement to identify the β-delayed proton precursor ⁹³ Pd, whose half-life has been measured to be 1.3±0.2s. The measured energy spectrum of β-delayed protons and relative branching ratios to the final states in the daughter nucleus ⁹²Ru are fitted by a revised statistic model calculation, and then the ground state spin of ⁹³Pd are assigned to be 9/2. Meanwhile, a nuclear energy-potential-surface (EPS) calculation is performed by using the Woods-Saxon Strutinsky method. The calculated result supports the ground state spin and parity of 9/2⁺ assignment.
