Yd. Zhang et al., COMMENT ON SPIN EVALUATION OF A NEUTRAL PARTICLE IN AN OSCILLATING MAGNETIC-FIELD - REPLY, Physics letters. A, 196(1-2), 1994, pp. 141-142
A.G. Wagh and V.C. Rakhecha noticed in their comment correctly that th
e geometric phase does not vanish if a static field exists besides the
oscillating field. Here we show that in case of a vanishing static fi
eld, the geometrical phase becomes zero or very small in case packet p
roperties are included.
