Data from the Jason-2 calibration/validation mission phase have been analyzed to identify the correlation between sea surface height (SSH) and significant wave height (SWH) errors. A cross-spectral analysis indicates that the SSH and SWH errors are n

A sensitivity analysis is performed on the level-2 algorithms for the Jason-2/Ocean Surface Topography Mission (OSTM). This analysis quantifies how inaccuracies in the fundamental measurements impact the overall sea-surface-height measurements. The a

In a recent experiment [Weinstein et al., Nature 395, 148 (1998)] we magnetically trapped 108 ground-state calcium monohydride molecules, CaH(X 2Σ,v″=0, J″=0). The molecules were prepared by laser ablation of a solid sample of CaH2 and loaded vi

Spectroscopy of buffer-gas cooled vanadium monoxide (VO) is performed in the presence of a magnetic trapping field and at low field. VO is created via laser ablation. A helium buffer gas, chilled by a dilution refrigerator, cools 1012 VO molecules to

The advent of buffer-gas loaded magnetic traps for atoms has opened the possibility of trapping paramagnetic molecules. We survey our results on the loading, trapping and spectroscopy of Eu atoms that demonstrated the technique. The principles govern

Atomic europium has been magnetically trapped using buffer-gas loading. Laser ablated $\mathrm{Eu}(^{8}S_{7/2})$ atoms are thermalized to 800 mK in a ${}^{4}\mathrm{He}$ buffer gas (to 250 mK in a ${}^{3}\mathrm{He}$ buffer gas). Anti-Helmholtz super

Elastic and inelastic collision-rate constants of {sup 52}Cr in the temperature range of 20 mK to 1 K are inferred from the evaporative cooling of buffer gas loaded atomic chromium. Using a model that describes the dynamics of the trapped chromium cl

Recent advances1,2,3,4,5 in the magnetic trapping and evaporative cooling of atoms to nanokelvin temperatures have opened important areas of research, such as Bose–Einstein condensation and ultracold atomic collisions. Similarly, the ability to tra

Recently we demonstrated the technique of buffer-gas loading of neutral species by using it to load a magnetic trap with europium atoms @1,2#. The atom density achieved in that experiment ( n;10 12 cm 23 ! is comparable to the highest densities achie
