Vibrational Levels of Ar4: New Odd-Parity Bosonic States

Xiaogang Wang, Tucker Carrington

Open publisher page 17 citations

Abstract

Vibrational levels of Ar4 are computed using the Lanczos algorithm and a large basis set. We find both even- and odd-parity states with wave functions that are invariant with respect to permutations of the Ar atoms. The odd-parity bosonic levels have not been computed previously. The even-parity levels are close to those obtained using the correlation-function Monte Carlo method (CFMC).
