Tables

Generic image for table
Table I.

Position (r m ) and value (ω0m ) of the minimum of lowest eigenpotential ω0(r) for different Rb N clusters. Length and energy are in units of Bohr and cm−1, respectively.

Generic image for table
Table II.

Comparison of ground state energetics for Rb N (N = 3 to 40) cluster and for He N (N = 3 to 9) cluster. E 0 is the ground state energy, is the ground state energy per particle, and ⟨V⟩ is the expectation value of the interaction energy. All energies are in cm−1.

Generic image for table
Table III.

Comparison of first few excited state energies of He and Rb clusters. E 1 , E 2 , E 3 are the energies of first, second, and third excited states, respectively. The energies are in cm−1.

Table IV.

Fitting parameters B N and C N for N = 4 − 9.
