We probe photoinduced loss for chemically stable bosonic Na23Rb87 and Na23K39 molecules in chopped optical dipole traps, where the molecules spend a significant time in the dark. We expect the effective two-body decay to be significantly suppressed due to the small expected complex lifetimes of about 13 and 6μs for Na23Rb87 and Na23K39, respectively. However, instead we do not observe any suppression of the two-body loss in parameter ranges where large loss suppressions are expected. We believe these unexpected results are most probably due to drastic underestimation of the complex lifetime by at least 1–2 orders of magnitude.

探索超冷非反应性玻色子Na23Rb87和Na23K39分子的光致二体损失

我们探测化学稳定玻色子的光致损失 23872339切碎的光学偶极子陷阱中的分子,其中分子在黑暗中度过了相当长的时间。由于预期的复杂寿命约为 13 和6μ 为了 23872339, 分别。然而,相反,我们没有观察到在预计会有大损失抑制的参数范围内对双体损失的任何抑制。我们认为这些意外的结果很可能是由于对复杂寿命的严重低估至少 1-2 个数量级。
