General Comments:

1994Og02, 1994Og03: 12C decay mode investigated, only upper limits were established for this decay mode

1997Gu22, 1995Gu10 (also 1995Gu01): first identified 114Ba from 58Ni(58Ni,2n) reaction and on-line mass separation (GSI). Three carbon events were reported by 1995Gu10 from ≈10×105 atoms of 114Ba, no α were found. But in later study 1997Gu22, no evidence has been found for the 12C decay mode. From a total of 5.4×104 17 114Ba atoms implanted, 1997Gu22 determine %12C<0.0034 (84% confidence limit)

1997Ja12: Delayed proton decay

2002Ma19 (also 2003Mb01,2003Ro08,2001Ro35): measured α decay, the energy of α: 3410 40

Theoretical calculation of 12C emission can be found in 1993Ka22, 1994De38, 1994Fu13 and 1995Po02
