a See also Tables <strong>14</strong>.15 and <strong>14</strong>.13, and footnote b in Table <strong>14</strong>.<strong>14</strong> here (86WA13).<br />
b I am indebted to E.K. Warburton for sending me a reanalysis <strong>of</strong> the E x <strong>of</strong> many <strong>of</strong> the<br />
states in <strong>14</strong> N with E x < 9.4 MeV: see, e.g., footnote b in Table <strong>14</strong>.<strong>14</strong>.<br />
c Weighted mean <strong>of</strong> values displayed in Table <strong>14</strong>.<strong>14</strong> <strong>of</strong> (86AJ01) but not using the value<br />
79 ± 7 fs which has not been published, and including the value 97.7 ± 5.5 fs(87ZI04).<br />
d Adopted value, based on values shown in Table <strong>14</strong>.<strong>14</strong> (86AJ01) andon5.6 ± 1.1 fs<br />
(87ZI04).<br />
e The present evidence (86WA13) only supports the presence <strong>of</strong> one state at E x ≈ 9.13<br />
MeV, with J =3 + . The only remaining evidence for a doublet is the 12 C( 3 He, p 0 ) <strong>14</strong> N(p)<br />
13 C g:s: work by (74NO01).<br />
f With the exception <strong>of</strong> <strong>14</strong> N*(16.91, 17.46, 21.8, 22.5, 23.0, 24.0), this state and all higher<br />
states were derived from an S-matrix analysis <strong>of</strong> the 12 C(d, α 1 ) reaction by (81JO02).<br />
g See, however, Tables <strong>14</strong>.20 and <strong>14</strong>.21.<br />

The energy <strong>of</strong> the 5.83 → 5.11 γ transition is E γ = 728.34 ± 0.10 keV. When corrected for<br />
the nuclear recoil and added to E x = 5105.89 ± 0.10 keV, E x = 5834.25 ± 0.<strong>14</strong> keV for <strong>14</strong> N*(5.83)<br />
