  The survey of different configurations near Fermi surface of 138Nd results in
12 lowest configurations, at both positive- and negative-deformations. These
are calculated to be the energetically lowest configurations. The results show
that, for both EDFs, the rotational states based on positive-minimum, which is
at gamma~35, are lower than the respective configurations with
negative-deformation. The general trends of the spin-versus-omega curve, and
the energy-versus-spin curve reproduce well those of the experimental data.
Further, for the observed bands `T1-T8', the calculated results using SLy4L
allows the configurations of the observed bands to be assigned. The
calculations predict transitional quadrupole moments, which can be used to
compare with future experimental data. The current cranked self-consistent
mean-field calculations of the near-yrast high-spin rotational bands in 138Nd
reproduce well the experimental data. The results suggest that the
experimentally observed bands can be assigned to the calculated bands with
various configurations at the positive-deformation. The predictions of the
current calculations are complementary to that of the well-know
macroscopic-microscopic calculations, both of which await future experiment to
verify.
