Photodissociation spectrum of Sr+Ne

The Sr+Ne complex is studied by laser photodissociation spectroscopy in a reflectron time-of-flight mass spectrometer. Two vibrational progressions and one continuum band are observed in the energy region between 23400 and 25250 cm(-1). The two progressions correspond to transitions from the X (2) Sigma(1/2) electornic ground state to the excited A (2) Pi(1/2) and A(2) Pi(3/2) spin-orbit states, while the continuum is attributed to transitions from X (2) Sigma(1/2) io the repulsive pan of the B-2 Sigma(1/2) excited state. From isotope-resolved measurements we assign the observed vibrational progressions and thus obtain the potential curves of the electronic states involved.
