Abstract
The determination of the maximum Lyapunov exponents in the 2/1 and 3/2 Jovian resonances (Ferraz-Mello 1994) suggested that the chaotic diffusion in the 2/1 resonance may be much faster than in the 3/2. As this fact could explain why the primordial population of the 2/1 resonance was removed (forming the Hecuba gap) and the 3/2-population was kept (Hilda group), we have decided to evaluate the diffusion speed for a large number of initial conditions using the frequency map analysis of Laskar (1988) (see also: Laskar 1996), adapted for the particular problem of Jovian resonances (Nesvorý and Ferraz-Mello 1997a). The ‘diffusion maps’ were also computed for the 4/3 Jovian resonance as it is, due to its similarity to the 3/2 resonance, a potential candidate for stable motion.
