Abstract Transition energies of neutral ytterbium (Yb I, Z = 70, belonging to the lanthanide series), including ionization potential, excitation energies, and electron affinity are calculated by the multiconfiguration Hartree-Fock (MCHF) method within the framework of the Breit-Pauli Hamiltonian and the relativistic Hartree-Fock (HFR) method. Ionization potential and excitation energies of Yb II and Yb III are also reported. The obtained results have been compared with other works.

Contamination Problem

A simple solution to the serious problem of specimen contamination in the electron microscope is presented. This is accomplished by the introduction of clean helium into the vacuum exactly at the specimen position. The local pressure gradient thus established inhibits the migration of hydrocarbon molecules to the specimen surface. The high ionization potential of He permits the use of relatively large volumes of the gas, without interfering with gun stability. The contamination rate is reduced on metal samples by a factor of 10.
