Title: Parametric excitation of {sup 87}Rb atoms in a quadrupole-Ioffe-configuration trap

Abstract

We have experimentally studied the parametric excitation of {sup 87}Rb atoms in a quadrupole-Ioffe-configuration trap. The temperature of an atomic cloud and number of trapped atoms versus time and modulation frequency of the parametric excitation field have been measured. We also noticed that the contribution of atomic collisions to the energy distributions can not be ignored in the case of weak excitation, which results in a lower temperature of the atomic cloud than by Gehm et al. [Phys. Rev. A 58, 3914 (1998)] predicted.
