Abstract

A neutron-deficient berkelium isotope of ²³⁴Bk produced via ¹⁹⁷Au(40Ar,3n) reaction and the daughter product of ²³⁰Am were newly identified. Alpha-decay energies of eleven ²³⁴Bk were found at 7.62-7.96 MeV, and six fission events that correlated with the α-decay of ²³⁴Bk were observed. The half-lives of ²³⁴Bk and ²³⁰Am were determined to be 19 +6-4 s and 32 +22 -9 s, respectively. The ²³⁴Cm followed by the β-decay of ²³⁴Bk was also identified.
