Mass of ⁹C: From the threshold energy of ⁷Be(³He, n)⁹C (MO71B) the atomic mass excess of ⁹C is 28.908 ± 0.004 MeV. This value is in good agreement with that obtained from the Q-value of ¹²C(³He, ⁶He)⁹C [28.912 ± 0.009 MeV]. See also (BA67A).

1. (a) 9C(β+)9B --> 8Be + p	Qm = 16.677

The half-life of ⁹C is 126.5 ± 1.0 msec (HA71B, ES72), 126.5 ± 2 msec (MO71B). Several groups of delayed protons are observed indicating the involvement of a number of ⁹B states: see Table 9.10 (in PDF or PS) (ES72). See also (HA65D). See also (BA66T, WI71K, WI72I, WI72L, TO73F; theor.).
