α-decay chain of the short-lived isotope ²²⁰Pa established using a digital pulse processing technique

RADIOACTIVITY ²²⁰Pa(α)[from ¹⁸⁷Re(⁴⁰Ar, 3nα), E=188 MeV at HIRFL-Lanzhou facility]; ²¹⁶Ac(α)[from ²²⁰Pa parent decay]; measured Eα, (evaporation residue)α-correlated events using the digital pulse processing technique, half-lives of decays of ²²⁰Pa and ²¹⁶Ac; deduced J, π of the ground state of ²²⁰Pa, and reduced α-decay width. Comparison with previous experimental Eα and T_1/2 for ²²⁰Pa.
