STRUCTURE AND INTERACTIONS OF CLUSTERS

Abstract

Ordered structures, which are characterized by the numbers T1 and T2 of nearest and next-nearest neighbors of the same kind in T1, T2 structure maps, can be classified in enthalpy and entropy stabilized structures. 111 three-dimensional structures MxNy with identical Ti values of all M and N particles were determined for the three-dimensional lattices. The numbers of shells were extended to i=11–18 to compare the values for closed shells with the magic numbers x and y of isotopes (M = proton , N = neutron ) or small clusters MxNy or Mx□y (□=vacancy). Electroneutral clusters were derived for 42 structures with x ≠ y. Colloidal DNA or proteins are clusters with different Ti values of each structural unit within long chains.
