GENERAL: See also (1984AJ01) and Table 9.1 [Table of Energy Levels] (in PDF or PS).

Model calculations: (1983KU17, 1984CH24, 1984VA06).

Special states: (1983KU17, 1984VA06).

Electromagnetic interactions: (1983KU17).

Astrophysical questions: (1987MA2C).

Complex reactions involving ⁹Li: (1983OL1A, 1983WI1A, 1984GR08, 1985JA18, 1985MA02, 1985MO17, 1986CS1A, 1986HA1B, 1986SA30, 1986WE1C, 1987BA38, 1987CH26, 1987JA06, 1987KO1Z, 1987SH1K, 1987TAZU, 1987WA09, 1987YA16, 1988CA06, 1988RU01, 1988ST06, 1988TA1A).

Reactions involving pions and other mesons (See also reactions 3 and 4.): (1985PN01).

Hypernuclei: (1982KA1D, 1983FE07, 1984AS1D, 1985PN01, 1986DA1B, 1986KO1A, 1986ME1F, 1987MI38, 1987PO1H, 1987WA36, 1988TA29).

Other topics: (1985AN28, 1985PO10, 1986AN07, 1987BA1I).

Ground-state properties of ⁹Li: (1983ANZQ, 1984CH24, 1985AN28, 1985SA32, 1987HA30, 1988JO1C, 1988POZS, 1988VA03).

[A preliminary report by (1988ARZU) gives Q = (0.69 ± 0.03) × Q(⁷Li).]

The interaction nuclear radius of ⁹Li is 2.41 ± 0.02 fm (1985TA18). [See also for derived nuclear matter, charge and neutron matter r.m.s. radii.]

1. 9Li(β-)9Be

Qm = 13.606

The half-life of ⁹Li is 178.3 ± 0.4 msec: see (1979AJ01). See also (1986CU01, 1988SA04). 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 (1984AJ01). See also (1986RO27), (1985HA1K) and (1983KU17; 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 (1979AJ01). See also (1984AJ01) 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 (1983SH19). For the earlier work see (1984AJ01).

4. 9Be(π-, γ)9Li

Qm = 125.962

Capture branching ratios to ⁹Li*(0, 2.69) are reported by (1986PE05).

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

Qm = 14.468

See (1984GL06: 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 (1979AJ01).
