The lifetime of a gas of ⁶Li atoms in a large hollow optical dipole trap formed by radiation with a frequency detuned by 4 or 2 GHz upward from resonance is measured. The trap has the shape of a thin-walled cylinder with flat bases and a volume of ∼1 mm³. The main mechanism responsible for the loss of atoms is heating due to Rayleigh scattering. The influence of collisions of atoms with the background gas and with each other on the measured lifetime is negligible.

近共振空心偶极阱原子的损失

测量了^{6 个}锂原子气体在由共振向上失谐 4 或 2 GHz 频率的辐射形成的大型空心光偶极陷阱中的寿命。捕集器呈薄壁圆柱体形状，底部平坦，体积约为 1 mm ³。造成原子损失的主要机制是瑞利散射引起的加热。原子与背景气体以及彼此碰撞对测量寿命的影响可以忽略不计。
