چکیده :
Zero-energy wave packets, coherent states, are constructed in such
a way that they retain their shape during the time evolution for a
large class of central potentials. The packets are not of the Gaussian
type with −r2 dependence but, instead, their shape is determined
by−r

μ+1/2 with−1/2 < μ < 1/2. A very close quantum–classical
correspondence is also shown, i.e., the well localized states travel
along suitable classical trajectories.
