The half-life of 15C is 2.449 ± 0.005 sec (1979AL23). Transitions have been observed to 15Ng.s. and to the upper of the 5.3 MeV states in 15N which has Jπ = 1/2+. Therefore Jπ(15Cg.s.) = 1/2+ or 3/2+. Weak transitions are observed to 15N*(7.30, 8.31, 8.57, 9.05) (1979AL23): see Table 15.16 (in PDF or PS). See also (1976AJ04) and (1977RI08, 1979AL23; theor.).
Observed proton groups are displayed in Table 15.2 (in PDF or PS). Angular distributions have been reported for E(7Li) = 1.7 to 20 MeV: see (1976AJ04).
|g| = 0.703 ± 0.012 for 15C*(0.74) (1980AS01). See also (1976AL16, 1979AL23).
At Eα = 65 MeV 15C*(0.74, 6.74, 7.35) are strongly populated. The angular distribution to 15C*(6.74 + 7.35) is consistent with L = 4 leading to Jπ = 7/2- and 9/2- for these two states on the basis of the (2J + 1) "rule" (1978JA10). See also (1976CE1E, 1976JA13). [However see Table 15.1 (in PDF or PS) for the density of states, and compare with the resolution of (1978JA10).]
