An empirical potential energy surface for He-Cl2(B 3∏u) based on a multiproperty fit

8 pags., 5 figs., 4 tabs.A report on empirical interaction surface for the He-Cl2(B 3IIu based on additive pairwise potentials was presented. The surface reproduced the Cl2 vibrational and rotational distributions with a level of quality achieved by the previous surfaces. The reported He-Cl2(B) empirical potential provided the best description of the spectroscopic and dynamical properties in the range of vibrational excitations.This work was supported by C.I.C.Y.T. ~Ministerio de Ciencia y Tegnologıa, Spain, Grant No. BFM-2001-2179, and by the European network TMR Grant No. HPRN-CT1999-00005
