Year: 2025
Type: article
Abstract: A search for a β -delayed fission ( β DF ) decay branch of isomerically pure samples of Au g 178 and Au m 178 was performed at the ISOLDE-CERN facility. Two complementary detection systems capable of registering α decays and fission fragments, the ISOLDE Decay Station and the ASET (Alpha SETup), were used. Despite very high statistics of produced Au 178 nuclei, no fission fragments were detected. Upper limits of β DF probabilities of P β DF ( Au g 178 ) < 1.11 ( 2 ) × 10 − 8 and P β DF ( Au m 178 ) < 9.7 ( 2 ) × 10 − 9 were determined. Corresponding lower limits of β DF partial half-lives were deduced as well, and the results are discussed in the context of experimental systematics of β DF in the neutron-deficient region of the nuclear chart.
