Temperature effects in the relaxation of optically oriented alkali vapours

摘要: A surprisingly high-temperature dependence of the spin relaxation times has been observed by different authors in optical pumping experiments with buffer gases. An interpretation these phenomena is given and a systematic experimental investigation presented. The method used completely from Franzen’s method. agreement between theory pretty good, except at very high temperature, when multiple diffusion becomes important. It shown that customary approach to problem may cause large errors values coefficient disorientation cross-section, be responsible for spread values, as they appear literature.
