 Title: A STUDY OF CORE NON-PENETRATING RYDBERG STATES OF CaF Creators: Ma, Hui; Liu, Y. M.; Li, J.; Polik, William F.; Cunningham, Kevin L.; Field, R. W. Issue Date: 1996 Publisher: Ohio State University Abstract: In a double resonance ionization experiment, calcium monofluoride v=1 $n^{*}$=14-18 Rydberg states were observed using a jet-cooled molecular beam and a time of flight mass spectrometer. Spectra were recorded via C $^{2}\Pi_{3/2} v=1$ intermediate states of both e and f symmetry and J=1.5 - 13.5. A preliminary assignment revealed that the strong features around integer $n^{*}$ were from the core non-penetrating f states. In the range of $n^{*}$=14-16, all seven components of each f complex were assigned. Term values were fitted to an effective f complex Hamiltonian which included coupling effects due to the core dipole and quadrupole $moments^{a}$. Description: $^{a}$ J. K. G. Watson, Mol.
