On the Structure of Low Lying 0^{+} Excited States of Pt isotopes
  The description of the of nuclei energy spectra of 0^{+} states has been done involving the degree of their collectivity as a systematics parameter. Within the framework of this approach the parameter of the collectivity is mainly determined by pairs of particles placed on single ''effective'' level and coupled to monopole bosons. Holshtein-Primakoff transformation of these monopole bosons leads to clear physical explanation of the structure of 0^{+} states in terms of ''ideal bosons''. The results may be helpful both for experimentalists and theorists in their investigations of low- lying states structure and transition probabilities.
