Abstract
We consider tunneling of a large spin between nonequivalent wells in t
he presence of the magnetic field. Using coherent spin states we show
that the quenching of tunneling for a half-integer spin, which occurs
at H = 0, survives up to a reasonably large field. An experiment is pr
oposed which may allow one to observe this quenching. Oscillation of t
he tunneling rate on the applied field is suggested.
