  A  286Fl α decay (166 MS) 

General Comments:

282Cn produced in four ways, three different α-decay chains, and directly in one correlated decay chain:

1. from α-decay chain 294Og -> 290Lv -> 286Fl -> 282Cn; 294Og produced in four correlated decay chains, but only two of these decay through α decay of 286Fl. See 294Og Adopted Levels, and 2012Og06, 2011Og07, 2006Og05, 2004Og10 and 2004Og12 for details.

2. from α-decay chain 290Lv -> 286Fl -> 282Cn. 290Lv produced in 12 correlated decay chains, but only seven of these decay through α-decay mode of 286Fl. See 290Lv Adopted Levels, and 2006Og05 and 2004Og07 for details.

3. from α-decay chain 286Fl -> 282Cn, where 286Fl is produced in 11 correlated decay chains, but only in six of these 286Fl decays by α-decay mode. See 286Fl Adopted Levels, and 2010El06, 2009St21, 2004Og12 and 2004Og10 for details.

4. 282Cn produced in 238U(48Ca,4n),E=240 MeV (2004Og12,2004OgZZ), where only one SF event is observed and assigned to 282Cn based on expected cross section, with energy of the evaporation residues (EVR)=10.8 MeV, energy of the SF event=222 MeV, and Δt(SF)=0.207 ms.

2018Ut02: 240Pu(48Ca,α2n),E=250 MeV at JINR-Dubna. Several SF decays with measured evaporation residue energy, decay time, and SF energy assigned were observed, eight of these events with 1-ms activity could belong to 282Cn or 284Fl, the latter through 4n-channel
