Mass of ⁸C: The atomic mass excess of ⁸C is 35094 ± 23 keV (2003AU03); Γ_cm = 230 ± 50 keV [J^π = 0⁺; T = 2]: see (1979AJ01). ⁸C is stable with respect to ⁷B + p (Q = -0.07 MeV) and unstable with respect to ⁶Be + 2p (Q = 2.14), ⁵Li + 3p (Q = 1.55) and ⁴He + 4p (Q = 3.51). At E(³He) = 76 MeV the differential cross section for formation of ⁸C_g.s. in the ¹⁴N(³He, ⁹Li) reaction is ≈ 5 nb/sr at θ_lab = 10°. The ¹²C(α, ⁸He)⁸C reaction has been studied at E_α = 156 MeV: dσ/dΩ ≈ 20 nb/sr at θ_lab = 20°: see (1979AJ01). See also (1985AN28) and (1987BL18, 1987SA15, 1988CO15, 1996GR21, 1996KA14, 1996SU24, 1997BA54, 1997PO12, 1998WI10, 1999HA61, 2000WI09, 2001CO21, 2003BA99).
