1983Hi12: W(⁴⁰Ar,xn) E(⁴⁰Ar)=180 MeV; products were separated from the primary beam by the velocity filter; parent of ²¹⁴Ra (7.16-MeV α). Tentative identification of ²²²U nuclide.

2012Ya04: ¹⁰⁰Mo(¹²⁴Sn,2n)²²²U,E(¹²⁴Sn)=505 MeV. Measured evaporation residues at the HRIBF-ORNL facility. Deduced production σ=21 nb +38-21 from in-beam data, and <270 nb from post-irradiation collection of decay product ²⁰⁶Po (from α decay chain: ²²²U |) ²¹⁸Th |) ²¹⁴Ra |) ²¹⁰Rn |) ²⁰⁶Po). No confirmed production and identification of ²²²U nuclide.

2015Kh09: ²²²U produced and identified in ¹⁷⁶Yb(⁵⁰Ti,4n), E(⁵⁰Ti)=231-255 MeV reaction. The ⁵⁰Ti¹²⁺ pulsed beam was produced by the UNILAC at GSI. Target=0.45 mg/cm² 5 thick ¹⁷⁶YbF₃ mounted on a rotating wheel, synchronized with the beam pulses. Evaporation residues (ERs), separated by using gas-filled TransActinide Separator and Chemistry Apparatus (TASCA) with flight time of 0.53 μs 6 through the separator, were implanted in a double-sided silicon strip detector. The events due to radioactive decays of implanted residues were selected from the events related to beam using a multiwire proportional counter (MWPC). Measured Eα, Iα, from Er-α correlated events from subsequent α-decay chains, half-lives of the parent nuclei corresponding to the evaporation residues, and successive α-decay daughters, the latter identified by their known characteristics in literature. The identification of ²²²U was made based on observed Er-α, two- or three-signal correlated events using a fast data acquisition and combined analog and digital (CANDI) readout system. α total of 81 Er traces were recorded for ²²²U and analyzed with subsequent α decay chain: ²²²U -> ²¹⁸Th -> ²¹⁴Ra. FWHM≈40 keV for 8.7 MeV α particles, recorded as single events, ≈110 keV and ≈180 keV for multiple α events stored in a single trace with time differences of 1 μs and 0.17 μs, respectively. Deduced α-decay reduced widths, and neutron shell gap, the latter compared with FRDM95 and HFB26 theoretical calculations for the Z=82-92,n=126 nuclei

2023Lu04: ²²²U produced in ¹⁸⁶W(⁴⁰Ar,4n),E(⁴⁰Ar)=188 MeV, followed by the separation of the evaporation residues (ERs) using the He-filled recoil separator SHANS at the HRIFL-Lanzhou facility. Measured α-α-correlated decay chains, Eα and T_1/2 for the decay of the g.s. of ²²²U from a total of ten observed events. Deduced reduced α-decay width and hindrance factor in Rasmussen’s formalism.
