“…We predict the existence of the molecular orbital bands that are possibly assigned to the α cluster states below α+ 18 O threshold energy observed in Ref. [25]. Above the α+ 18 O threshold energy, the existence of the α+ 18 O molecular bands that correspond to the observed bands [26,28] are also shown.…”

“…These bands start form the states below the α+ 18 O threshold energy and they can be assigned to the observed α cluster states below the α+ 18 O threshold energy reported in Refs. [24,25]. The σ orbital of 22 Ne is an analog of that of Be isotopes.…”

“…The α reduced width is given in the unit of the Wigner limit θ 2 α = γ 2 α /γ 2 W . The calculated and observed [25] ratios of the α reduced width to that of the ground state are also shown.…”

“…cluster wave function [26,28]. Disconnected squares show the observed states by the α-transfer reaction [25].…”

“…In particular, experimental and theoretical information on α clustering of this nucleus is not enough compared to 20 Ne. Experimentally, to my knowledge, α clustering in 22 Ne was investigated first by W. Scholz et al [24,25] based on the α transfer reaction on 18 O. They reported the significant α clustering of 10 natural parity states lying between 6.24 and 8.59 MeV (3.4 and 1.0 MeV below the α+ 18 O threshold energy).…”
