Energy levels in light nuclei
The recent application of the shell model theory to the energy level structure of light nuclei has made apparent a lack of experimental data concerning these nuclei. The impossibility of accurately criticizing the theory ...
Analysis of low frequency whistler wave occurrences in the night-side Venus ionosphere
This body of work deals with a detailed analysis of plasma, magnetic, and electric field data from Pioneer Venus Orbiter (PVO) to determine if the data are consistent with the possibility of lightning on Venus. This has ...
Internal conversion spectra from heavy and medium weight nuclei
Abstract Not Available.
Lifetime of helium metastable spin-states in a helium discharge
The lifetime of a helium 23s1 metastable atom electronic spin-state is measured in helium gas using optical pumping techniques. The metastable atoms are created by an RF electrical discharge. The spin-state lifetime is ...
A study of the urban heat island of Houston, Texas
The magnitude, spatial extent, growth, and seasonal and diurnal behaviors of the urban heat island of Houston, Texas are characterized using both in situ air temperature and remotely sensed surface temperature data. Between ...
Novel permanent-magnet Penning trap for studies of dipole-bound negative ions
Low-energy electron transfer between a Rydberg atom and a target molecule can result in formation of long-lived metastable negative ions. Here we describe a novel permanent-magnet Penning trap designed to examine the ...
Interaction of Xenon Rydberg Atoms with Conductive Surfaces: The Effects of Stray Fields
The ionization of xenon Rydberg atoms at metallic surfaces is examined. The data show that, when the effects of stray electric "patch" fields present on the surface are taken into account, ionization is well described by ...
Modeling of laser-generated radiative blast waves, with applications to late-term supernova remnants
The goal of laser astrophysics is to provide a means by which aspects of specific astrophysical phenomena can be reproduced in the laboratory. Although the hydrodynamic instabilities of early supernova remnants have already ...
DIFFERENTIAL CROSS SECTIONS FOR NEUTRAL-NEUTRAL COLLISIONS
Collisions of fast ions and neutral atoms with other atoms and molecules are important in a broad range of physical phenomena. A new technique, based on the use of a micro-channel plate position-sensitive detector, has ...
The kicked atom: Characterization of quasi-one-dimensional Rydberg atoms and their nonlinear dynamics
The characteristics of strongly-polarized quasi-one-dimensional (quasi-1D) Rydberg atoms produced by photoexcitation of selected Stark states in the n = 350 Stark manifold are investigated by studying their ionization ...
