Attempts to study this nucleus in the ³H(t, p), ⁷Li(⁶Li, ⁸B) and ⁹Be(α, ⁸Be) reactions, as well as in ⁷Li + π^- have been unsuccessful: no sharp states are observed [see (74AJ01, 79AJ01)]. A recent study of the spectrum of π⁺ from ⁷Li + π^- suggests that ⁵H may be nearly stable to decay into ³H + 2n (SE81G). The work of (AD67E) on the ³He(³He, n)⁵Be reaction suggested, on the basis of analog considerations, that ⁵H is unstable by more than 2.1 MeV to decay into ³H + 2n. See also (SE81I) and (AV81B, BE81D; theor.).
