Israelsson, U. E.; Duncan, R. V., 1993, "Design of a Low Gravity Simulator for Performing Non-Equilibrium Investigations near the Lambda Transition of ^4He", https://hdl.handle.net/2014/35381, ['Bulletin of the American Physical Society', 'Seattle, Washington'], JPL Open Repository
A design is presented of a low gravity simulator where a magnetic field gradient is employed to oppose the hydrostatic pressure effects of gravity. It appears feasible to reduce the effective gravity environment of the helium in the cell by about two orders of magnitude. The corr... |

Toth, R. A., 1993, "The v1-v2, v3-v2, v1, and v3 bands of H216O: line positions and strengths", https://hdl.handle.net/2014/34957, UNKNOWN, JPL Open Repository
High-resolution spectra of H216O were recorded with a Fourier-transform spectrometer covering transitions in the (100)-(010), (001)-(010), (100)-(000), and (001)-(000) bands. The measured line frequencies were used to determine high accuracy values of rotational energy levels in... |
