Abstract This paper reports the experimental results on electromagnetically induced absorption (EIA) spectra observed in the system which does not satisfy completely the conditions given by Lezama et al [1999 Phys. Rev. A 59 4732]. EIA signals on the transitions in the Cs line are able to be observed, where as open systems. Theoretical model of Lezama et al is good for the case , considering spontaneous transfer of atomic coherences or populations this model is not able to explain our experimental results obtained in the case . This paper offers a theoretical model which is able to well explain the case . It also uses this theoretical model to explain the split and shift of EIA peaks, which have been obtained in experiments.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
