Query: Neutrino Oscillations in Intermediate States.II -- Wave Packets   We analyze oscillations of intermediate neutrinos in terms of the scattering
of particles described by Gaussian wave packets. We study a scalar model as in
a previous paper (I) but in realistic situations, where the two particles of
the initial state and final state are wave packets and neutrinos are in the
intermediate state. The oscillation of the intermediate neutrino is found from
the time evolution of the total transition probability between the initial
state and final state. The effect of a finite lifetime and a finite relaxation
time are also studied. We find that the oscillation pattern depends on the
magnitude of wave packet sizes of particles in the initial state and final
state and the lifetime of the initial particle. For $\Delta m^2_{21}=3\times
10^{-2}$ eV$^2$, the oscillation probability deviates from that of the standard
formula if the wave packet sizes are around $10^{-13}$ m for 0.4 MeV neutrino.
