Phys. Rev. A 67, 043408 (2003) [6 pages]Photoassociation spectroscopy of cold calcium atomsReceived 5 December 2002; published 22 April 2003 Photoassociation spectroscopy experiments on 40Ca atoms close to the dissociation limit 4s4s1S0-4s4p1P1 are presented. The vibronic spectrum was measured for detunings of the photoassociation laser ranging from 0.6 to 68 GHz with respect to the atomic resonance. In contrast to previous measurements, the rotational splitting of the vibrational lines was fully resolved. Full quantum-mechanical numerical simulations of the photoassociation spectrum were performed which allowed us to put constraints on the possible range of the calcium scattering length between 50a0 and 300a0. © 2003 The American Physical Society URL:
