  We study quantum resonance behavior of the infinite-range kinetic Ising model
at zero temperature. Numerical integration of the time-dependent Schr\"odinger
equation in the presence of an external magnetic field in the $z$ direction is
performed at various transverse field strengths $g$. It is revealed that two
resonance peaks occur when the energy gap matches the external driving
frequency at two distinct values of $g$, one below and the other above the
quantum phase transition. From the similar observations already made in
classical systems with phase transitions, we propose that the double resonance
peaks should be a generic feature of continuous transitions, for both quantum
and classical many-body systems.
