1. 15C(β-)15N

Qm = 9.7717

The half-life of ¹⁵C is 2.449 ± 0.005 s (79AL23). 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⁺. The log ft to ¹⁵N*(5.30) indicates an allowed transition: 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) (79AL23): 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 (84WA07). See also (86AS1B, 88AS1A), (88WA1E) and (89BA92, 89PO1K; 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 groups are displayed in Table 15.3 (in PDF or PS). See also (81AJ01).

4. 13C(α, 2p)15C

Qm = -18.9013

See (81AJ01).

5. 14C(n, γ)15C

Qm = 1.2181

σ_γ < 1 μb (81MUZQ).

6. 14C(d, p)15C

Qm = -1.0065

At E_{pol. d} = 16 MeV angular distributions and A_y measurements are reported to a state at E_x = 4.78 ± 0.10 MeV (γ_c.m. = 1.74 ± 0.40 MeV); S = 0.5. A narrow state at E_x = 5.81 ± 0.02 MeV (γ_c.m. = 64.3 ± 8.1 keV), S = 0.02, is also observed. It is suggested that these are 1p2h and 3p4h 3/2⁺ states (85DA23) [and S.E. Darden, private communication]. For the earlier work see Table 15.2 (in PDF or PS).

7. 14C(13C, 12C)15C

Qm = -3.7283

Angular distributions have been studied at E(¹³C) = 20.0 to 27.5 MeV to ¹⁵C*(0, 0.74) (88BI11). See also (90VO1E).

8. 15N(π-, γ)15C

Qm = 129.797

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) (83ST04).

9. 16O(7Li, 8B)15C

Qm = -22.624

At E(⁷Li) = 82 MeV ¹⁵C*(0, 3.1) are populated (85AL1G).
