Synopsis We present a comprehensive analysis of autoionization processes in Ne clusters (∼5000 atoms) after
multiple valence excitations by free electron laser radiation. The evolution from 2-body interatomic Coulombic
decay (ICD) to 3-body ICD is demonstrated when changing from surface to bulk Frenkel exciton excitation. Super
Coster-Kronig type 2-body ICD is observed at Wannier exciton which quenches the main ICD channel.
Previously, Yase at al [1] investigated multiple
excitation of Wannier type excitons (correspond-
ing to the 2p → 3d atomic resonance) at 20.26
eV in Ne clusters by the intense extreme ultra-
violet free electron laser (EUV-FEL) at SCSS
(SPring-8 Compact SASE Source, Japan) and
found that the electron emission is dominated by
low energy electron emission that originates from
a nanoplasma.
In the present experiment, we have extended
our observations to multiple excitations of surface
and bulk Frenkel type excitons (corresponding
to the 2p → 3s atomic resonance) at 17.12 eV
and 17.65 eV, respectively, using the new seeded
EUV-FEL, FERMI (Trieste, Italy) [2].
At the lowest surface Frenkel exciton we can
clearly see the pure 2-body ICD peak at ∼11.5 eV,
predicted by Kuleff at al [3], with its multistep
ICD tail which is similar to direct multistep ioniza-
tion in Ar clusters [4]. The situation changes for
the bulk Frenkel exciton, where the broad struc-
ture around 5 eV is identified as 3-body ICD of
knock-off type (also known as collective autoion-
ization [5]) and becomes dominant over 2-body
ICD at high FEL intensities. For the Wannier ex-
citon we can see complete quenching of the main
2-body ICD by super Coster-Kronig type ICD
in which one 3d electron relaxes to a 3s orbital
and another 3d electron is ejected with ∼1.8 eV
kinetic energy (see Fig. 1).
