摘要：
An invariant Hermitian operator is constructed for the Heisenberg spin system in a time-dependent magnetic field. Using it we obtain the general solution of the Schrodinger equation for this system. By virtue of the general solution, the geometric phase of Pancharatnam type is worked out. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
