26.41> =(aeffir 0:75 )m=s (1) where R c is the radius of a cometary nucleus in km, ae and ffi are particle's radius and density both in CGS units. The maximumdifferences between orbital semi-major axis \Deltaa and the eccentricity \Deltae of the ejected meteoroid from those of the comet will be (Plavec 1955): \Deltaa = \Sigma6:72 \Theta 10 \Gamma5 a 2 c v p 2=r \Gamma 1=a c AU \Deltae = \Sigma6:72 \Theta 10 \Gamma5 re c v p 2=r \Gamma 1=a c (2) where a c and e c are semi-major a
