摘要: High-spin states of the 22Ne nucleus in excitation energy range 15–30 MeV have been studied. The angular correlation method has used to determine spins excited states. A number new with high momenta—20.0 (9−), 20.7 (11−), 21.6 22.2 (12+), and 25.0 (9−)—have revealed. They are intensely populated reaction 14C(12C, α1)22Ne* → α2 + 18O correspond rotational bands various structures.
