Abstract
The mean life of the 2795 keV
1
+
2
level in
21Ne has been measured using the
21C(
13C, αγ)
21Ne reaction and a variant of the Doppler-shift attenuation method. The result obtained was
τ = 7.9 ± 1.8 fs. In addition, the separation of the 2789 (
1
−
2)
and 2795 (
1
+
2
) keV levels in
21Ne been measured as 5.91 ± 0.31 keV. The relevance of both results to measurements of parity mixing in
21Ne is discussed.
