Mass of ⁹Li: From the threshold for ⁹Be(d, 2p)⁹Li, E_d = 19 ± 1 MeV (GA51C), the mass excess of ⁹Li is determined as M - A = 28.1 ± 1 MeV.

1. 9Li(β-)9Be* --> 8Be + n

Qm = 12.4

⁹Li decays to excited states of ⁹Be which decay by neutron emission. The mean of the reported half-lives is 0.169 ± 0.003 sec (GA51C, HO52B). See also (SH52, FR53A, BE55D, FL56, TA58B).

2. 9Be(d, 2p)9Li

Qm = -15.5

The threshold is 19 ± 1 MeV (GA51C).

3. 11B(γ, 2p)9Li

Qm = -31.4

See (SH52, TA58B).

4. 12C(γ, 3p)9Li

Qm = -47.3

See (RE53, TA58B).

The following reactions are not reported: ⁷Li(t, p)⁹Li (Q_m = -2.9), ⁹Be(n, p)⁹Li (Q_m = -13.3), ⁹Be(t, ³He)⁹Li (Q_m = -14.1) and ¹¹B(n, ³He)⁹Li (Q_m = -23.6).
