We present a detailed study of the Og-(P3/2) pure long-range electronic state of the 87Rb2 molecule. The high resolution spectral data provided by photoassociative spectroscopy of 87Rb2 is analised by using the generalized simulated annealing method. The dipole matrix element of the 5p 87Rb atomic state and other effective asymptotic parameters for the Og-(P3/2) long-range state are determined and a complete analytical description of the potential wellis obtained. We extract a radiative lifetime of the 5P3/2 and 5P1/2 states equal to 26.25(8) ns and 27.75(8) ns, respectively, with a precision (0.3%) comparable to atomic physics experiment.

Abstract
We present a detailed study of the Og-(P3/2) pure long-range electronic state of the 87Rb2 molecule. The high resolution spectral data provided by photoassociative spectroscopy of 87Rb2 is analised by using the generalized simulated annealing method. The dipole matrix element of the 5p 87Rb atomic state and other effective asymptotic parameters for the Og-(P3/2) long-range state are determined and a complete analytical description of the potential wellis obtained. We extract a radiative lifetime of the 5P3/2 and 5P1/2 states equal to 26.25(8) ns and 27.75(8) ns, respectively, with a precision (0.3%) comparable to atomic physics experiment.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
