“…The present measurements were performed at the Vivitron accelerator facility using a 140 MeV 18 O beam of intensity 2.5 pnA. The beam was incident on a 120 µg cm −2 self-supporting 12 C target, and an α-transfer reaction was used to populate states in 22 Ne. The break-up of the 22 Ne ejectile into 14 C + 8 Be was detected using two charged-particle telescopes.…”

“…The energy splitting of the two bands has been described in terms of the tunnelling of the α-particle between the two sides of the 16 O cluster core. Other rotational bands in the 20 Ne nucleus have been classified in terms of their particle-hole, or cluster, structure [4], and there is evidence for states associated with a 12 C + α + α configuration [5].…”

“…Such states would be the analogues of 16 O + 2α cluster states in 24 Mg. Similarly, the 12 C cluster core provides a foundation for the formation of 12 C + 2α cluster structures in 20 Ne. The well-documented resonances in this latter system (e.g.…”

A search for continuum levels in ' Ne with a large [' O(Oz+ )+a] parentage has been conducted using both resonant and direct production processes. The differential cross section for the ' 0(a, al)' 0 (02+) reaction has been measured at 13 to 26 angles for bombarding energies from E = 10.2 to 18 MeV, mostly in 25 keV steps. Events leading to the first excited state in ' 0 were identified by requiring the coincident observation of an a particle and an electron or positron from the internal pair decay of the ' 0 first excited state. Amplitudes of individual partial waves were extracted from the data by parametrizing the angular distributions in terms of the complex zeros of the scattering amplitudes. An R-matrix analysis of the data reveals a J =2+ level at E =13.1 MeV with a spectroscopic factor 8 )63%. 1 Several individual levels, a region of overlapping J =4+ levels from E, =13.69 to 14.93 MeV and a region of J =6+ levels from E"=16.73 to 18.73 MeV, have also been analyzed in detail. Branching ratios of Ne levels to the first excited state in ' 0 have been measured by populating the levels with the reaction ' C(' C, n) Ne* and observing their subsequent a decay to the 02+ state of ' 0. A J"=6+ level at E"=15. 16 MeV and a J =8+ level at E"=18. 54 MeV, which had previously been suggested as members of a rotational band based on the J =0+ level in Ne at E"=12. 44 MeV are shown to have small values of 6,arguing against this identification.
