Chapter 3. Alpha-Cluster Study of⁴⁰Ca and⁴⁴Ti by the (⁶Li,d) Reaction

High precisionY89(α,α)Kiss1, Mohr2, Fülöp3 et al. 2009Phys. Rev. C

“…The properties of α clustering above shell closures in the even-even nuclei 44 Ti = 40 Ca ⊗ α, 94 Mo = 90 Zr ⊗ α, and 212 Po = 208 Po ⊗ α have been studied extensively [7,[28][29][30][33][34][35][36][37][38]. However, only a few studies are available for even-odd nuclei below the above-mentioned shell closures [39][40][41].…”

α-Cluster States in Intermediate Mass Nuclei

“…It has been stated that this "concept of α-clustering is essential for understanding the structure of light nuclei" [3], and this concept has been extended to heavy nuclei (e.g. [4,5,6,7,8,9,10]). …”

“…Suppl. 132, [3,4,5,6,7,8,9,10]). However, there is no stable doubly-magic nucleus with the magic neutron number N = 50.…”

$ \alpha$ α -cluster states in 46,54Cr from double-folding potentials

“…212 Po = 208 Pb ⊗ α, 44 [3,4,5,6,7,8,9,10]. Very recently, Souza and Miyake [1] (hereafter: S&M) have extended these studies towards the chromium isotopes.…”
