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.
