Query: Effects of Time-Odd Components in Mean Field on Large Amplitude
  Collective Dynamics   We apply the adiabatic self-consistent collective coordinate (ASCC) method to
the multi-O(4) model and study collective mass (inertia function) of the
many-body tunneling motion. Comparing results with those of the exact
diagonalization, we show that the ASCC method succeeds in describing gradual
change of excitation spectra from an anharmonic vibration about the spherical
shape to a doublet pattern associated with a deformed double-well potential
possessing the oblate-prolate symmetry. The collective mass is significantly
increased by the quadrupole-pairing contribution to time-odd components of the
moving mean field. In contrast, the cranking (Inglis-Belyaev) mass based on the
constrained mean field, which ignores the time-odd components, is smaller than
the ASCC mass and fails to reproduce the exact spectra.
