Gerton, Jordan | Dipolar relaxation collisions in magnetically trapped 7Li | We report the measurement of the rate constant for dipolar relaxation from the (F=2, mF=2) hyperfine state of 7Li. The atoms are confined in a permanent magnet trap at a field of 10^3 G. The measured value of (1.05±0.10)X10^-14 cm3/s agrees well with theory. Additionally, we determine an upper bo... | 1999-02 | |

Gerton, Jordan | Measurements of collective collapse in a Bose-Einstein condensate with attractive interactions | The occupation number of a magnetically trapped Bose-Einstein condensate is limited for atoms with attractive interactions. It has been predicted that, as this limit is approached, the condensate will collapse by a collective process. The measured spread in condensate number for samples of 7Li atom... | 1999-02 | |

Vardeny, Zeev Valentine | Stimulated emission in high-gain organic media | Stimulated emission was studied in various scattering gain media, including thin p-conjugated polymer films, organic dyes-doped gel films, and opal crystals saturated with polymer and laser dye solutions. We found that at high excitation intensities a featureless amplified spontaneous emission ban... | Stimulated emission; High-gain organic media; pi-conjugated polymers; Scattering gain media; Organic dyes-doped gel films; Opal crystals | 1999-02 |
