Abstract

The stability range of the two molecular systems H2+ and H2, whose particles interacted through the Yukawa potential, with varying screening parameter λ was investigated using quantum Monte Carlo technique. Variational Monte Carlo (VMC) calculations were carried out using a one-term function as trial wave function, to optimize the parameters of the trial wave functions for each value of λ. H2 was found to be stabler than H2+ for larger value of λ. H 2 being the only stable system for λc>1.375 bohr-1 was found to be in the borromean state.
