States in 21Ne via the 12C(13C, αγ)21Ne reaction
Andritsopoulos G., Catford WN., Garman EF., Pringle DM., Fifield LK.
Many gamma-decaying levels up to 8.25 MeV in 21Ne have been populated via the 12C(13C, α)21Ne reaction at E13c = 19.7 McV. Gamma-rays de-exciting these levels were detected in coincidence with α-particles, making it possible to study the γ-decay of individual levels in isolation. A variant of the Doppler shift attenuation method due to Branford and Wright was used to measure the lifetimes of most of the states observed. The relevance of the information obtained to hand structure in 21Ne is discussed. Shell-model calculations are also presented for positive-parity states, and compared with the available experimental information. © 1981.
