The x-ray absorption spectrum of ${\mathrm{N}}_{2}^{+}$ in the K-edge region has been measured by irradiation of ions stored in a cryogenic radio frequency ion trap with synchrotron radiation. We interpret the experimental results with the help of re

We have performed X-ray absorption spectroscopy of size-selected, free, cationic, transition-metal-doped (Sc, Ti, V, Cr) gold clusters in a size range n = 1–9. The electronic configuration of the impurity atom was determined by modeling the X-ray a

The size dependent electronic structure and separate spin and orbital magnetic moments of free Co$_n^+$ ($n = 4\;\textrm{-}\;9$) cluster ions have been investigated by x-ray absorption and x-ray magnetic circular dichroism spectroscopy in a cryogenic

The $^{4}\Phi_{9/2}$ ground state of the Ni$_2^+$ diatomic molecular cation is determined experimentally from temperature and magnetic-field-dependent x-ray magnetic circular dichroism spectroscopy in a cryogenic ion trap, where an electronic and rot

Soft landing of mass-selected clusters in rare gas matrices is a technique used to preserve mass selection in cluster deposition. To prevent fragmentation upon deposition, the substrate is covered with rare gas matrices to dissipate the cluster kinet

Spin and orbital magnetic moments of cationic iron, cobalt, and nickel clusters have been determined from x-ray magnetic circular dichroism spectroscopy. In the size regime of $n = 10 - 15$ atoms, these clusters show strong ferromagnetism with maximi

Small, mass-selected Cr n clusters soft landed onto a (1×1)O/Ru(001) substrate were investigated by near-edge X-ray absorption spectroscopy. Cr n X-ray absorption spectra exhibit size-dependent shifts of L 3 absorption edges. Furthermore, strong clu
