Abstract We investigate the high resolution photoassociation spectra of 85Rb2 molecules in 0u+ long range state below the (5S1/2 + 5P1/2) asymptote. The 85Rb atomic samples are trapped in a dark magneto-optical trap (MOT) and prepared in the dark state. With the help of trap loss technique, we obtain considerable photoassociation spectroscopy with rovibrational resolution, some of which have never been observed before. The observed spectrum is fitted by a rigid rotation model, and the rotational constants of ultracold 85Rb2 molecule in long range 0u+ are obtained for different vibrational states. By applying the LeRoy-Bernstein method, we assign the vibrational quantum numbers and derive C3 coefficient, which is used to obtain the potential energy curve.

Online attention
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.
