Access: Use of this item is restricted to the UNT Community
Interview with Navy veteran Frank H. Bigelow, survivor of the siege of Corregidor. The interview includes Bigelow's personal experiences about being a prisoner-of-war of the Japanese during World War II, boyhood in North Dakota, various jobs during the Great Depression, and enlisting in the Navy. Additionally, Bigelow speaks about volunteering for duty in the Philippines and his assignment to the submarine tender USS Canopus, pre-war military life in the Philippines, the Japanese bombing of Cavite Navy Yard and the destruction of the Canopus, retreating to Bataan and to Corregidor, the fall of Corregidor, his confinement in the 92nd Garage area, the forced march down Dewey Boulevard in Manila and confinement at Cabanatuan, hell ship to Japan, coal mining for Mitsui Heavy Industries, the amputation of his leg by fellow prisoners after a mining accident, liberation, and the destruction in Nagasaki due to the atomic bomb. The interview includes an appendix with an article titled "A Soldier's Story."

RESONANT X-RAY SCATTERING AS A PROBE OF ORBITAL AND CHARGE ORDERING. (open access)

RESONANT X-RAY SCATTERING AS A PROBE OF ORBITAL AND CHARGE ORDERING.

Resonant x-ray scattering is a powerful experimental technique for probing orbital and charge ordering. It involves tuning the incident photon energy to an absorption edge of the relevant ion and observing scattering at previously ''forbidden'' Bragg peaks, and it allows high-resolution, quantitative studies of orbital and charge order--even from small samples. Further, resonant x-ray scattering from orbitally ordered systems exhibits polarization- and azimuthal-dependent properties that provide additional information about the details of the orbital order that is difficult, or impossible, to obtain with any other technique. In the manganites, the sensitivity to charge and orbital ordering is enhanced when the incident photon energy is tuned near the Mn K absorption edge (6.539 keV), which is the lowest energy at which a 1s electron can be excited into an unoccupied state. In this process, the core electron is promoted to an intermediate excited state, which decays with the emission of a photon. The sensitivity to charge ordering is believed to be due to the small difference in K absorption edges of the Mn{sup 3+} and Mn{sup 4+} sites. For orbital ordering, the sensitivity arises from a splitting--or difference in the weight of the density of states [239]--of the orbitals occupied by …
