On the interatomic Coulombic decay in the Ne dimer

Abstract

The interatomic Coulombic decay (ICD) in the Ne dimer is discussed in view of the recent experimental results. The ICD electron spectrum and the kinetic energy release of the Ne+ fragments resulting after Coulomb explosion of Ne2 (2+) are computed and compared to the measured ones. A very good agreement is found, confirming the dynamics predicted for this decay mechanism. The effect of the temperature on the electron spectrum is briefly investigated.

Competition of inelastic electron scattering and Interatomic Coulombic Decay in Ne clusters

“…We also note that both ICD peaks do not extend towards zero eV on the kinetic energy axis, which is in contrast to experiments on dimers [9,24].…”

2s-Excitation and Photoionization of Neon Clusters

“…The dominant Fano-profiles of the atom are shifted in energy and the corresponding exciton profiles of the solid are significantly broadened. The present work is also related to previous studies on Ne 2s photoionization of dimers and clusters, which were discussed in terms of the Interatomic Coulombic Decay (ICD) in the Ne 2s-regime [17][18][19][20]. Furthermore, 2p correlation satellites in variable size neon clusters were investigated before by photoemission [21,22].…”

Experimental Separation of Virtual Photon Exchange and Electron Transfer in Interatomic Coulombic Decay of Neon Dimers

“…Extensive theoretical work has been carried out on ICD in neon clusters [5][6][7][8][9][10] and many other species [1,11]. For the case of ICD after 2s photoionization in neon dimers, the decay rate is proportional to jV L2p;R2p;L2s;k ÿ V L2p;R2p;k;L2s j 2 , where the two electron-electron Coulomb matrix elements (2) are denoted as ''direct'' and ''exchange'' contribution, respectively [6,12].…”
