7H (2002TI10)

(Not illustrated)

7H has not been observed. Attempts have been made to detect it in the spontaneous fission of 252Cf (1982AL33) and in the 7Li(π-, π+) reaction [see (1984AJ01)]. A study of 9Be(π-, 2p) (1987GO25) found no evidence for 7H. See also the review of (1989OG1B) and the 7Li(π-, π+) investigation reported in (1989GR06). The ground state is calculated to have Jπ = 1/2+ and to be unstable with respect to 1n, 2n, 3n and 4n emission. Excited states are predicted at 4.84, 5.00 and 6.96 MeV, with Jπ = 3/2+, 5/2+, and 5/2- [(0 + 1)ℏω model space] and at 3.88, 3.94 and 5.99 MeV with Jπ = 3/2+, 5/2+ and 1/2+ [(0 + 2)ℏω model space] (1985PO10). See also references cited in (1988AJ01).
