摘要: Abstract For the first time, mass distribution of nickel, cobalt and iron clusters is analyzed in a large range with near threshold photoionization experiments standard time-of-flight spectrometry. In case nickel cobalt, oscillations observed spectra correspond to icosahedral atomic shell structure studied (50–800 atoms). clusters, situation less clear. The exact location structures depends on source operating conditions. We have competition between different cluster geometries.
