Query: High-spin structures of $^{136}_{54}$Xe, $^{137}_{55}$Cs,
  $^{138}_{56}$Ba, $^{139}_{57}$La, and $^{140}_{58}$Ce : A shell model
  description   In the present work recently available experimental data [A. Astier et al,
Phys. Rev. C 85, 064316 (2012)] for high-spin states of five N=82 isotones,
$^{136}_{54}$Xe, $^{137}_{55}$Cs, $^{138}_{56}$Ba, $^{139}_{57}$La, and
$^{140}_{58}$Ce have been interpreted with state-of-the-art shell model
calculations. The calculations have been performed in the 50-82 valence shell
composed of $1g_{7/2}$, $2d_{5/2}$, $1h_{11/2}$, $3s_{1/2}$, and $2d_{3/2}$
orbitals. We have compared our results with the available experimental data for
excitation energies including high-spin states, occupancy numbers and
transition probabilities. As expected the structure of these isotones are due
to proton excitations across Z=50 shell. The structure of the positive-parity
states are mainly from $(\pi g_{7/2}\pi d_{5/2})^n$ and $(\pi g_{7/2}\pi
d_{5/2})^{n-2}(\pi h_{11/2})^2$ configurations, while the negative-parity
states have $(\pi g_{7/2}\pi d_{5/2})^{n}(\pi h_{11/2})^1$ configuration.
Additionally, for the $^{136}_{54}$Xe, $^{137}_{55}$Cs and $^{138}_{56}$Ba
isotones the excitation of the neutrons across N=82 gap is important.
