Journal ArticleDOI
Properties of hollow molecules probed by single-photon double ionization.
Pascal Lablanquie,Pascal Lablanquie,Francis Penent,Francis Penent,Jérôme Palaudoux,Jérôme Palaudoux,Lidija Andric,Lidija Andric,P. Selles,P. Selles,Stéphane Carniato,Stéphane Carniato,Klemen Bučar,Matjaž Žitnik,Marko Huttula,John H. D. Eland,Eiji Shigemasa,Kouichi Soejima,Yasumasa Hikosaka,Isao H. Suzuki,M. Nakano,K. Ito +21 more
TL;DR: Detailed properties are presented such as the spectroscopy, formation, and decay dynamics of the N(2)(2+) K(-2) main and satellite states and the strong chemical shifts of double K holes on an oxygen atom in CO, CO2, and O2 molecules.
Journal ArticleDOI
Evidence of single-photon two-site core double ionization of C2H2 molecules.
Pascal Lablanquie,Tasko P. Grozdanov,M Zitnik,Stéphane Carniato,Stéphane Carniato,P. Selles,P. Selles,Lidija Andric,Lidija Andric,Jérôme Palaudoux,Jérôme Palaudoux,Francis Penent,Francis Penent,H. Iwayama,Eiji Shigemasa,Yasumasa Hikosaka,Kouichi Soejima,M. Nakano,Isao H. Suzuki,K. Ito +19 more
TL;DR: A simple theoretical model based on the knockout mechanism gives reasonable agreement with experiment on the formation in a single-photon transition of two core holes, each at a different carbon atom of the C2H2 molecule.
Journal ArticleDOI
Double-Core-Hole States in Neon: Lifetime, Post-Collision Interaction, and Spectral Assignment.
Gildas Goldsztejn,Tatiana Marchenko,Ralph Püttner,Loic Journel,Renaud Guillemin,Stéphane Carniato,P. Selles,Oksana Travnikova,Denis Céolin,Alexsandre F. Lago,Raimund Feifel,Pascal Lablanquie,Maria Novella Piancastelli,Maria Novella Piancastelli,Francis Penent,M. Simon +15 more
TL;DR: Using synchrotron radiation and high-resolution electron spectroscopy, specific photoelectrons from K^{-2}V states in neon corresponding to simultaneous 1s ionization and 1s→valence excitation are directly observed and identified.
Journal ArticleDOI
Single Photon K − 2 and K − 1 K − 1 Double Core Ionization in C 2 H 2 n ( n = 1 – 3 ), CO, and N 2 as a Potential New Tool for Chemical Analysis

TL;DR: The cross section variation for single photon K(-1)K (-1) double core ionization in the C(2)H(2n) sequence and in the isoelectronic C(1-3) hydrocarbon sequence, N (2) and CO molecules validates a knock-out mechanism in which a primary ionized 1s photoelectron ejects another 1s electron of the neighbor atom.
Journal ArticleDOI
Near-edge x-ray absorption fine structures revealed in core ionization photoelectron spectroscopy.
M. Nakano,P. Selles,P. Selles,Pascal Lablanquie,Pascal Lablanquie,Yasumasa Hikosaka,Francis Penent,Francis Penent,Eiji Shigemasa,K. Ito,Stéphane Carniato,Stéphane Carniato +11 more
TL;DR: A theoretical model is proposed providing absolute photoionization cross sections and revealing clear signatures of direct (monopolar) and conjugate (dipolar near-edge x-ray absorption fine structure) shakeup lines of comparable magnitude.
