to be synthesized was 288 mc in 2004 there are five known radioisotopes from 286 mc to 290 mc the longest lived isotope is 290 mc with a half life of 0 65 seconds the isotopes undergo alpha decay into

used to form compound nuclei with z 115 each entry is a combination for which calculations have provided estimates for cross section yields from various neutron evaporation channels the channel with

date 243 am 48 ca 291 mc 8 9 successful reaction 241 am 48 ca 289 mc planned reaction 243 am 44 ca 287 mc reaction yet to be attempted hot fusion edit hot fusion reactions are processes that create compound nuclei at high excitation energy 40 50 mev hence hot leading to a reduced probability of survival from fission the excited nucleus then decays to the ground state via the emission of 3 5 neutrons fusion reactions utilizing 48 ca nuclei usually produce compound nuclei with intermediate excitation energies 30 35 mev and are sometimes referred to as warm fusion reactions this leads in part to relatively high yields from these reactions 238 u 51 v x n 289 x mc edit there are strong indications that this reaction was performed in late 2004 as part of a uranium iv fluoride target test at the gsi no reports have been published suggesting that no product atoms were detected as anticipated by the team 10 243 am 48 ca x n 291 x mc x 2 3 4 5 edit this reaction was first performed by the team in dubna in july august 2003 in two separate runs they were able to detect 3 atoms of 288 mc and a single atom of 287 mc the reaction was studied further in june 2004 in an attempt to isolate the descendant 268 db from the 288 mc decay chain after chemical separation of a 4 5 fraction 15 sf decays were measured with a lifetime consistent with 268 db in order to prove that the decays were from dubnium 268 the team repeated the reaction in august 2005 and separated the 4 and 5 fractions and further separated the 5 fractions into tantalum like and niobium like ones five sf activities were observed all occurring in the niobium like fractions and none in the tantalum like fractions proving that the product was indeed isotopes of dubnium in a series of experiments between october 2010 february 2011 scientists at the flnr studied this reaction at a range of excitation energies they were able to detect 21 atoms of 288 mc and one atom of 289 mc from the 2n exit channel this latter result was used to support the synthesis of tennessine the 3n excitation function was completed with a maximum at 8 pb the data was consistent with that found in the first experiments in 2003 this reaction was run again at five different energies in 2021 to test the new gas filled separator at dubna s she factory they detected 6 chains of 289 mc 58 chains of 288 mc and 2 chains of 287 mc for the first time the 5n channel was observed with 2 atoms of 286 mc 11 242 pu 50 ti p x n 291 x mc x 2 edit this reaction was studied by the team in dubna in 2024 for the first time a p x n reaction was successful with actinide targets and 48 ca 50 ti 54 cr projectiles producing one atom of the known 289 mc in the p2n channel evaporating one proton and two neutrons 12 reaction yields edit the table
