[PDF] Top 20 α-cluster resonances in light nuclei

... The DC-60 cyclotron [6] accelerates heavy ions up to the 1.9 MeV / A energy. The TTIK tech- nique [3] is used in the measurements. The incoming ions are slowed down and stopped in a helium (or hydrogen) gas of the ... See full document

... two α clusters are formed. Once the 2 α core is formed, molecular orbitals are constructed by the linear combination of p-orbits around each α cluster and valence neutrons occupy the molecular ... See full document

... Because the number of alpha particles in the nucleus is more than two, so this many-particle system can be made from a variety of geometric arrangements of four alpha particles. Therefore the structure of the ground ... See full document

... Why do I find this so exciting? We already know that T is not an exact symmetry because of the non- vanishing phase of the CKM matrix, which, however, does not seem enough to generate the observed matter-antimatter ... See full document
