Recent results from Yakutsk experiment: development of EAS, energy spectrum and primary particle mass composition in the energy region of 10^15-10^19 eV
Experimental data obtained at the Yakutsk array after the modernization in
1993 are analyzed. The characteristics of EAS longitudinal and radial
development found from the charged particle flux and EAS Cherenkov light
registered at the Yakutsk complex array are presented. The energy spectrum of
EAS obtained from Cherenkov light and an estimate of the PCR mass composition
are presented.Comment: 10 pages, 11 figures. Invited talk on XIV ISVHECRI; to be published

The spectrum features of UHECRs below and surrounding GZK
The energy spectrum of UHECRs is discussed on the basis of the Yakutsk array
database analysis. In the region E=0.1 to 30 EeV the showers are detected under
trigger-500, while at energies above 30 EeV the whole acceptance area for
trigger-1000 is used in order to utilize all the data available in the region
of GZK cutoff.Comment: Invited talk at CRIS2004: GZK and surroundings, Catania, Italy,
