The TASISpec consisted of a 288FL7c cube-like configuration of 0.31-mm thick, 32x32-strip double-sided 288FL8c silicon strip detector (DSSD) and four 0.97-mm thick 16x16-strip DSSDs. 288FL9c The Si detector system was surrounded by an array detectors for |g and 288FL9c x-ray detection, five composite Ge detectors, one Cluster Ge detector 288FLAc and four Compex detectors, each with four crystals. A total of 32 decay 288FLBc chains were assigned to candidate Flerovium decay chains (30 of which 288FLCc concluded with beam-off fission), out of which two were firmly assigned 288FLDc to {+286}Fl, eleven to {+288}Fl, and one to {+286}Fl or {+288}Fl 288FLEc (ambiguous E|a value). The remaining eighteen decay chains were 288FLFc candidates for {+289}Fl, which the authors stated would be discussed 288FLGc in another publication. 288FL c In the analysis of half-life of the decay of {+288}Fl and E|a from its 288FL2c decay, previously observed decay chains from the following references 288FL3c were also included: 288FL4c 1. 2004Og12: Phys.
