“…The largely p-shell character of these states is evident in pickup reactions. The first five states are observed in the 13 C(d, 3 He) 12 B reaction [34] and the 3 + state is clearly seen in the 14 C(p, 3 He) 12 B reaction [33]. The 12 C analogs of all six states are excited strongly in the 15 N(p, α) 12 C reaction [35] in accordance with p-shell predictions [36,37].…”

Energy and width of the excited0+state inO12

“…[5] probably contains both 0 + and 2 + states. In the reaction 16 O(α, 8 He) 12 O, an excited state was suggested at 1.1 MeV [6].…”

“…By isospin symmetry, the 14 O(p,t) reaction should have certain features in common with the reaction 14 C(p,t) [8] to the T = 2 states of 12 C. It is customary to refer to the 12 Be states as parents, to the T = 2 states of 12 C as double analogs, and to the 12 O states as mirrors. For clarity, we use that language here.…”

“…A calculation [12] of the 12 Be-12 O mass difference, plus a simple (sd) 2 shell-model calculation, produced a wave function containing 68% (sd) 2 and 32% p shell that has provided remarkable agreement with a variety of processes involving 12 Be(g.s.). These processes include beta decay [13], Coulomb energy [12], neutron removal [14], 14 C(p,t) [15][16][17], 14 O(p,t) [2,18,19], B(E2) [19][20][21], and Gamow-Teller transitions from 12 B [22]. A summary is given elsewhere [23].…”
