Statistical Properties Of The Rovibrational Bound Levels For Ar2kr

We calculate the rovibrational bound levels with total angular momentum J = 0, 1 of (Ar2Kr)-Ar-40-Kr-84 trimer using the slow variable discretization method combined with the finite-element method-discrete variable representation basis. The statistical distributions of the rovibrational levels for J(Pi)= 0(e), 1(e), and 1(o) symmetries are presented and the effects of the Axilrod-Teller potential term are considered. For the 0(e) and 1(e) symmetries, the Axilrod-Teller term makes the spectra become fully chaotic. However, for the 1(o) symmetry, statistical properties depend mainly on the coupling between K = 0 and K = 1 and the Axilrod-Teller term has a small effect. Published by AIP Publishing.
