✦ Synopsis

The pholofragment time-of-flight (TOF) spectra of Arz (4~n66) were measured in the wavelength range of 465-585 nm.

The photofragment observed were Ar+ and A$. Analysis of the TOF spectra revealed that the angular and the kinetic energy distributions of the Ar* fragment resemble those observed in the photodissociation of Ar:. This finding indicates that an Ar: chromophoric core is solvated by neutral Ar atoms in Ari (4<n< 6) and the photophysical properties of A$ remains almost intact in these cluster ions. The dynamics of the Ar: formalion was explained by the intracluster internal conversion in the photoexcited trimer core ion.
