Abstract：

The proton-rich isotope¹⁴⁶Ho was produced via the fusion-evaporation reaction⁹²Mo (⁵⁸Ni, 3p1n). The β-delayed proton decay of¹⁴⁶Ho was studied by proton-γ coincidence measurements using a He-jet tape transport system. The γ-transitions in¹⁴⁵Tb following the proton emissions were observed, and the β-delayed proton branching ratios to the final states in the grand-daughter nucleus¹⁴⁵Tb were determined. According to the relative branching ratios, the ground-state spin of¹⁴⁶Ho has been proposed and the possible configuration discussed.
