Description

The dα-coincidence spectra from the reaction 16O(6Li,d)20Ne*(α)16O are measured with high statistical accuracy. The results of the measurements allow to state the level E* = 13.7 MeV, Jπ = 7-, Γ = 310 keV, Γα/Γ = 0.51, θα2 = 0.84 in the 20Ne nucleus is not exist. The conclusion about its existence made as a result of α-particle elastic scattering on 16O excitation function analysis is erroneous

Abstract (Russian)

Измерены с высокой статистической точностью спектры dα-совпадений из реакции 16O(6Li,d)20Ne*(α)16O. Результаты измерений позволяют утверждать, что в ядре 20Ne уровня с характеристиками Е* = 13,7 МэВ, Jπ = 7-, Γ = 310 кэВ, Γα/Γ = 0,51, θα2 0,84 не существует. Вывод о существовании этого уровня, сделанный на основе анализа функции возбуждения упругого рассеяния α-частиц на ядре 16О, ошибочен
