15O+α resonant elastic scattering to study cluster states in19Ne [Presentation]
(Institute of Physics Publishing, 2017)Clustering phenomena are well known in nuclear physics for stable nuclei, both α-conjugate (N=Z, A=2N), like8Be,16O,20Ne, and non-α-conjugate, like6Li and7Li. In general, it is expected that light exotic nuclei may also ...
