【 摘 要 】

A refinement to the theory published by Finn et al. is presented here. Compression effects are taken into account by a rigorous definition of the plasma length and by modifying the expression of the velocity field. The perturbation of the plasma length is calculated exactly by a suitable Green function. Growth rates and real frequencies of the unstable m(omega)=1 mode are compared with the experimental values, showing a good agreement when compression effects are strong(i.e., for short traps).
