1. 9Li(β-)9Be

Qm = 13.606

The half-life of ⁹Li is 178.3 ± 0.4 msec: see (79AJ01). See also (86CU01, 88SA04). ⁹Li decays to a number of states in ⁹Be: see reaction 12 in ⁹Be and Table 9.7 (in PDF or PS). The nature of the decay to ⁹Be*(0, 2.43) with J^π = 3/2^-, 5/2^- is evidence for J^π = 3/2^- for ⁹Li_g.s.. The probability for delayed neutron decay, P_n, is (49.5 ± 5)%: see (84AJ01). See also (86RO1L), (85HA1K) and (83KU17; theor.).

2. 7Li(t, p)9Li

Qm = 2.386

Protons are observed to excited states at E_x = 2.691 ± 0.005, 4.31 ± 0.02, 5.38 ± 0.06 and 6.430 ± 0.015 MeV. The widths of the three highest states, which are unbound, are 100 ± 30, 600 ± 100 and 40 ± 20 keV, respectively. Angular distributions have been studied at E_t = 11.3, 15 and 23 MeV. At the highest energy they are consistent with J^π = 3/2^-, 5/2^- is evidence for J^π = 3/2^-, 1/2^- and >/= 9/2 for ⁹Li*(0, 2.69, 6.43): see (79AJ01). See also (84AJ01) and ¹⁰Be.

3. 9Be(γ, π+)9Li

Qm = 153.175

The angular distribution of the π⁺ to ⁹Li_g.s. has been measured at E_e = 200 MeV (83SH19). For the earlier work see (84AJ01).

4. 9Be(π-, γ)9Li

Qm = 125.962

Capture branching ratios to ⁹Li*(0, 2.69) are reported by (86PE05).

5. 9Be(7Li, 7Be)9Li

Qm = 14.468

See (84GL1E: E(⁷Li) = 78 MeV).

6. 11B(6Li, 8B)9Li

Qm = -25.121

At E(⁶Li) = 80 MeV the angular distribution to ⁹Li_g.s. has been measured. States at E_x = 2.59 ± 0.10, 4.36 ± 0.10 and 6.38 ± 0.12 MeV are also populated: see (79AJ01).
