Mass of ⁶Be: From the Q-value of the ⁶Li(p, n)⁶Be reaction (BO57I), and using the Wapstra masses (WA55C) for ⁶Li, ¹H and n, the mass excess (M - A) of ⁶Be is 20.3 ± 0.2 MeV (see also (55AJ61)).

1. (a) 3He(3He, 2p)4He	Qm = 12.858	Eb = 10.4
(b) 3He(3He, p)5Li	Qm = 11.062

The total cross section shows a monotonic increase for E(³He) = 100 to 800 keV. At E(³He) = 200 keV, it is at least 2.5 μb. Below E(³He) = 350 keV, the cross section fits the simple Gamow exponential form. At higher energies, partial waves of l >/= 2 appear to be required (GO54C). See also (AL53A).

2. (a) 3He(α, n)6Be	Qm = -9.2
(b) 4He(3He, n)6Be	Qm = -9.2

Not observed.

3. 6Li(p, n)6Be

Qm = -5.2

At E_p = 9 MeV, a neutron group is observed with Q = -5.2 ± 0.2 MeV; the reported ground-state width is < 300 keV (BO57I).

4. 6Li(3He, t)6Be

Qm = -4.5

Not observed.
