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.
