276MT c {+280}Rg produced in |a-decay chain: {+288}Mc -> {+284}Nh -> {+280}Rg;
276MT2c {+288}Mc produced in {+243}Am({+48}Ca,X) reaction. See {+288}Mc Adopted
276MT3c Levels for details of production of this isotope.
276MT c 2012Og02, 2013Og01: measured E|a, decay times.
276MT c 2013Ru11: measured E|a, E|g, |a|g-coin; deduced first level scheme of
276MT2c {+276}Mt
276MT c 2015Ga24: measured E|a, E|g, |a|g-coin; deduced level scheme of
276MT2c {+276}Mt in conjunction with the work of 2013Ru11. No K x-rays were
276MT3c observed
276MT cA $HF=T{-1/2}{+exp}/T{-1/2}{+sys}, where experimental half-life of
276MT2cA {+280}Rg was used as 4.1 s {I+5-4}, based on data from 2015Ga24,
276MT3cA and those in 2013Ru11 and 2013Og01. The systematic half-life was
276MT4cA from the formalism of 2009Qi07.

276MT cA E$from E|a(max)=10.31 MeV {I2} (2015Ga24), interpreted as
276MT2cA E|a=9.86 MeV {I2}+(E|g=452.7 {I25}), observed in |a|g-coincidence.
276MT3cA 2015Ga24 concluded that E|a-max is larger compared to adopted
276MT4cA E|a-max=10.01 MeV {I1}, and considered it as a random coincidence and
276MT5cA did not include in the level scheme.
