    "abstract": "Photoassociation spectroscopy experiments on 40Ca atoms close to the\ndissociation limit 4s4s 1S0 - 4s4p 1P1 are presented. The vibronic spectrum was\nmeasured for detunings of the photoassociation laser ranging from 0.6 GHz to 68\nGHz with respect to the atomic resonance. In contrast to previous measurements\nthe rotational splitting of the vibrational lines was fully resolved. Full\nquantum mechanical numerical simulations of the photoassociation spectrum were\nperformed which allowed us to put constraints on the possible range of the\ncalcium scattering length to between 50 a_0 and 300 a_0.",
