Vibrational Band Origins of ⁷Li₂⁶Li⁺ and ⁶Li₂⁷Li⁺

Abstract

The vibrational band origins of ⁷Li₃⁺, ⁷Li₂⁶Li⁺ and ⁶Li₂⁷Li⁺ were calculated by using the t-coordinate vibrational Hamiltonian of Carney et al. The results for ⁷Li₃⁺ and ⁷Li₂⁶Li⁺agree with those of Henderson et al.obtained by using a body-fixed scattering coordinate Hamiltonian. No vibrational band origins for ⁶Li₂⁷Li⁺ have so far been reported.
