Clustering aspects in 20Ne Alpha-conjugate Nuclear System
Journal Title: Journal of Nuclear Physics, Material Sciences, Radiation and Applications - Year 2018, Vol 5, Issue 2
Abstract
The clustering aspects in alpha-conjugate nuclear system 20Ne has been investigated comparatively within microscopic and macroscopic approaches of relativistic mean field theory (RMFT) and quantum mechanical fragmentation theory (QMFT), respectively. For the ground state of 20Ne, the matter density distribution calculated within RMFT, depict the trigonal bipyramidal structure of 5α’s and within QMFT, the equivalent α+16O cluster configuration is highly preformed. For excited state corresponding to experimental available energy, the QMFT results show that in addition to α+16O clusters, other xα-type clusters (x is an integer) are also preformed but in addition np-xα type (n, p are neutron and proton, respectively) 10B clusters are having relatively more preformation probability, due to the decreased pairing strength in liquid drop energies at higher temperature. These results are in line with RMFT calculations for intrinsic excited state which show two equal sized fragments, probably 10B clusters.
