Atom loss from the trap and total collisioncrosssection can be inferred from the knowledge of the density of background gases.
在获知背景气体密度的条件下,可以计算出原子损耗和完全碰撞截面。

Xenon is a very heavy element, and thus has a larger crosssection for collision with a WIMP.
氙气是一个非常沉重的元素,因而具有更大的跨越与懦夫相撞一节。

Moreover, the average collisioncross-section between a slow electron and a neutral particle is measured at several different temperatures using both the interferometer and the transmission methods.
