Cationic reactions of methylene cyclobutane

June 1, 1976
Author(s)
Anzor Mikaia, Evgenyi Finkelstein, Valentin Vdovin, Nikolay Nametkin
Dimerization, alkylation and metathesis reactions are studied for methylenecyclobutane in a benzene solution in the presence of catalysts

Flame Spread of Carpet Systems Involved in Room Fires.

June 1, 1976
Author(s)
K M. Tu, S Davis
This study was designed to test the hypothesis that given a situation where a chair or other item of furniture becomes the first item to burn in a room (providing the ceiling and walls are noncombustible), there is little reason to expect involvement of

Improved Microwave-discharge Source for uv Photoemission

April 1, 1976
Author(s)
Theodore Vorburger, B Waclawski, D Sandstrom
A microwave-discharge uv light source has been improved to yield significant photon fluxes at 26.9 and 40.81 eV. In order to optimize the 26.9-eV (NeII) and 40.81-eV (HeII) radiation, the discharge was operated at 2.5 Pa (0.019 Torr) in an external

Core Level Shifts in the 3d Transition Metals and Tin

March 15, 1976
Author(s)
R E. Watson, M L. Perlman, J F. Herbst
We present estimates of various contributions to the free-atom-metal binding-energy shifts, Δ}E B, for the 2>s and 2p core levels of teh iron series elements and, for comparison, the 3 d s/2 level of Sn. Our results indicate that the sharp break in the

4f Excitation Energies in Rare-Earth Metals: Relativistic Calculations

February 15, 1976
Author(s)
J F. Herbst, R E. Watson, J W. Wilkins
We describe calculations of 4f electron binding energies for the rare-earth metals. Relativistic Hartree-Fock calculations for atomic configurations most closely approximating those of the metals are initially performed, and crystal potentials are

Effect of Ground State and Excitation Potentials on Energy Levels of Ni Metal

February 15, 1976
Author(s)
R E. Watson, J F. Herbst, L Hodges, B I. Lundqvist, J W. Wilkins
Self-consistent energy-band calculations for paramagnetic Ni have been performed in an effort to compare ground-state and excitationpotential prescriptions; potentials of the Hartree-Fock-Wigner-Seitz and Hedin-Lundqvist type are examined. We find the
