MINUTES OF THE 1993 FALL MEETING OF THE TEXAS SECTION OF
THE AMERICAN PHYSICAL SOCIETY
22-23 October l993; College Station, Texas

General Information

The annual Fall Meeting of the Texas Section of The American Physical Society was held on the campus of Texas A&M University in College Station, Texas, on 22-23 October 1993.

A total of 510 persons, including 219 students, registered for the meeting, which was held jointly with the Texas Section of the American Association of Physics Teachers and Zone 13 of the Society of Physics Students.

Plenary sessions on "Frontiers of Physics" featured invited talks on "Status Report and Future of the Efforts to Measure the Electron Neutrino Rest Mass" (Manfred Fink, UT Austin); "Laser Probes of the MACRO and Micro Cosmos" (Marlan O. Scully, Texas A&M); "Update on the Search for the Top Quark" (Fred Bird, SSC Laboratory); and "Quantum Mechanics and Precision Measurements", (Norman F. Ramsey, Harvard). Professor Ramsey gave a second talk in a special SPS Session on "Time and the Physical Universe".

Two invited symposia were organized. The first on Quantum Optics,chaired by Edward S. Fry, included: "Phase of the Quantum Harmonic Oscillator-How to Read Your Wristwatch" (Scott Shepard, Baylor); "Lasing Without Population Inversion" (G.G. Padmabandu, Texas Laser Laboratory); "The Gamma Ray Laser: Issues and Progress in 1993" (James J. Carroll, Center for Quantum Electronics); "A Feasible Realization of the Einstein-Podolsky-Rosen Gedanken Experiment" (Edward S. Fry, Texas A&M); and "Proton Correlations and Interferences in Complimentary Spaces" (G. Agarwal, University of Hyderabad).

The second Symposia on Applied Physics in Microelectronics, chaired by John Lowell included: "Characterization of the Effects of Poly Resistivity in a 0.8 Micrometer Polycide Gate CMOS Circuit" (Robert Dawson and Barry Sheffield, Advanced Micro Devices); "Nitrogen Distribution and Resultant Electrical Characteristics of N_2O Gate Oxynitrides Grown in an RTP and in a Conventional Furnace" (Y. Okada, P. Tobin, S. A. Ajuria and R. T. Hegde, Motorola); "Recent Progress in Vacuum Microelectronic Field Emission Devices for Flat Panel Applications" (Mark Weichold, Texas A&M); "Probing Randomly-Oriented Interface Roughness in Si(100)SiO_2 and H- Terminated Si(100) Surfaces Using Second Harmonic Generation" (J.L. Dudap, Q. Deng, M.C. Downer, UTAustin; B. Doris, Motorola; J. D. Lowell, Advanced Micro Devices, and A. C. Diebold, Sematech); "The Termal Redistribution of Fluorine Implanted into Silicon and Polysilicon: A SIMS-XTEM Study" (V. S. Kaushik, R. L . Hance, P. T. Tobin, and H. H. Tsong, Motorola); and " A Comparison of Heavy Ion Backscattering Spectrometry (HIBS), Total Reflection X-Ray Fluorescence (TXRF) and Surface Analysis by Resonant Ionization of Sputtered Neutrals (SARISA)" (A. C. Diebold, Sematech).

An informal SPS session on Graduate Programs in Texas was arranged with brochures, posters and spokespeople available to help prospective graduate students find out what is available.

There were 122 APS contributed papers arranged into 11 sessions covering most areas of physics, 29 AATP contributed papers in 3 sessions, and 8 SPS papers. The AAPT Section also arranged 16 workshops on physics education topics for area teachers.

The Chairs' Breakfast on Friday morning was attended by 29 persons. The luncheon, attended by 177, was followed by a brief business meeting. The Banquet was attended by 250 persons who were treated to a lecture and demonstration on the physics of violins by Professor Joseph Nagyvary, Texas A&M University. The lecture was followed by a brief chamber music concert featuring Texas Section's Joe Ham on piano and Bob Kenefick on violin.

Once again, the student competition was a rousing success. The awards for outstanding student papers were supported by donations from Houston Advanced Research Center(HARC) and Texas Fireframe Co. and by the Section's general operating fund. A committee chaired by Past Chair Michael Gorman reviewed the presentations of the 53 graduate students and 11 undergraduate students competing and selected thirteen students to receive awards. Receiving a $200 award for the highest composite score was George Lengel, Texas A&M. Receiving awards of $150 were: V. Ambrose, Texas Christian; K. T. Andrews, Texas A&M; J. Engbrecht, Trinity; P. Ferrell, SSC; B. Joelson, Texas A&M; Y. D. Kim, U. North Texas; J. C. McCoy, Texas A&M; Katherine Ocker, Sam Houston State; T. Sauncy, Texas Tech; M. A. Seabolt, East Texas State; S. L. Stephenson, Baylor; and P. E. Tissot, Texas A&M.

Secretary-treasurer C. A. Quarles reported that as of October 13, 1993 there was a balance of $18,806.60 in the Section accounts with a reasonable uncertainty.
