Ground state of ¹⁵C:(1984FR13).

1. 15C(β-)15N

Qm = 9.7717

The half-life of ¹⁵C is 2.449 ± 0.005 sec (1979AL23). Transitions have been observed to ¹⁵N_g.s. and to the upper of the 5.3 MeV states in ¹⁵N which has J^π = 1/2⁺. Therefore J^π (¹⁵C_g.s.) = 1/2⁺ or 3/2⁺. Weak transitions are observed to ¹⁵N*(7.30, 8.31, 8.57, 9.05) (1979AL23): see Table 15.15 (in PDF or PS). The shape of the ¹⁵C_g.s. → ¹⁵N_g.s. transition differs appreciably from an allowed shape (1984WA07). See also (1981FR23), (1983SN03) and (1980RI06; theor.).

2. 9Be(7Li, p)15C

Qm = 9.092

Observed proton groups are displayed in Table 15.2 (in PDF or PS).

3. 13C(t, p)15C

Qm = 0.9127

Observed proton groups are displayed in Table 15.3 (in PDF or PS) (1983TR12). |g| = 0.703 ± 0.012 for ¹⁵C*(0.74) (1980AS01).

4. 13C(α, 2p)15C

Qm = -18.9013

At E_α = 65 MeV ¹⁵C*(0.74, 6.74, 7.35) are strongly populated: see (1981AJ01).

5. (a) 14C(n, γ)15C	Qm = 1.2181
(b) 14C(n, n)14C		Eb = 1.2181

σ_γ < 1 μb (1981MUZQ). See also (1976AJ04).

6. 14C(d, p)15C

Qm = -1.0065

Observed proton groups are displayed in Table 15.2 (in PDF or PS).

7. 14C(14C, 13C)15C

Qm = -6.9584

See (1981FR23, 1985KO04).

8. 15N(π-, γ)15C

Qm = 129.796

Radiative pion capture shows evidence for J^π = 5/2⁺, T = 3/2 giant magnetic quadrupole states: transitions are reported to ¹⁵C*(0.74) as well as to ¹⁵C*(6.7, 8.6, 12.0) (1983ST04).
