For the ground state of <sup>20</sup>Ne, the matter density distribution calculated within RMFT, depict the trigonal bipyramidal structure of 5α’s and within QMFT, the equivalent α+<sup>16</sup>O cluster configuration is highly preformed. For excited state corresponding to experimental available energy, the QMFT results show that in addition to α+<sup>16</sup>O 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) <sup>10</sup>B 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.</p> ER -
