Abstract
A method determines a total velocity average cross-section parameterσνin a relationship of the form Γ(U)=nσν·ƒ(U, U), where: Γ(U) is a rate of exponential loss of sensor atoms from a cold atom sensor trap of trap depth potential energy U in a vacuum environment due to collisions with residual particles in the vacuum environment; nis a number density of residual particles in the vacuum environment; Uis a parameter given by which relates the masses of the sensor atoms mand residual particles mto the total velocity average cross-section parameterσν; and ƒ(U, U) is a function of the trap depth potential energy U and the parameter Uwhich models a naturally occurring dependence of the loss rate Γ(U) on the trap depth potential energy U and the parameter U, where ƒ(U=0, U) is unity for all U.
