Structure and Thermodynamic Stability of PuC2(g) Molecules

Based on the RECP for Pu atom and 6-311G*basis sets for C atom, the structure and thermodynamic functions for PuC2(g) have been calculated by theab initiomethod, and the formed thermodynamic functions for PuC2(g)molecules have been calculated by theab initiomethod, and the formed thermodynamic functions for PuC2(g) molecules have beenworked out by the thermodynamic method. The calculation results showthat PuC2(g) molecules have no thermodynamic stability.
