Responsibility to Optical Pumping for Binary Mixtures of Rb Isotope
摘要
Abstract
Investigation of optical pumping for binary mixtures may provide information on the interaction between atomic systems and open up possibility to control response time. Considered Rb isotope ~(85)Rb and ~(87)Rb as binary mixtures, optical pumping response can be observed with using square modulated field at 10Hz and two channels of RF sources for NMR of ~(85)Rb and ~(87)Rb respectively. Based on proposed model of three energy levels, unitary system or binary mixtures of ~(85)Rb and ~(87)Rb can be accurately described with an exponential function. According to the relation of response time between binary and unitary, the response time for mixtures is contributed from unitary ones and their concentrations.关键词
