Using $448.1\times 10 ^6$ $\psi(3686)$ decays collected with the BESIII detector at BEPCII $e^+e^-$ storage rings, branching fractions and angular distributions of $\chi_{cJ}\to\Xi^-\bar{\Xi}^+$ $\Xi^0\bar{\Xi}^0$ $(J = 0, 1, 2)$ are measured based on a partial-reconstruction technique. The $\chi_{c1}\to\Xi^0\bar{\Xi}^0$ $\chi_{c2}\to\Xi^0\bar{\Xi}^0$ observed for first time statistical signifi...
