✦ Synopsis

We study the vibrational predissociation of the van der Waals molecule Ne . . 12(B3v) by Using a quasiclassical trajectory method. The potential energy surface assumed was a simple sum of pairwise atom-atom interactions. According to approximate quantal calculations, the necessary initial conditions were obtained and the relevant Hamilton equations were numerically solved. In the range of initial vibrational excitations of 1; 36 5 u I 56, two crossover levels are found, which are reflected in the vibrational distributions of the diatomic fragment as in the halfwidth J? for vibrational predissociation. Our present results for Ne . . . I,( B) are in agreement with the so-called "energy gap law" when compared with similar ones for He.. . I,( B).
