Query: Observation of double pygmy resonances in $^{195,196}$Pt and enhanced
  astrophysical reaction rates   Our measurements of $^{195,196}$Pt $\gamma$-strength functions show a
double-humped enhancement in the $E_{\gamma}= 4-8$ MeV region. For the first
time, the detailed shape of these resonances is revealed for excitation
energies in the quasicontinuum. We demonstrate that the corresponding
neutron-capture cross sections and astrophysical reaction rates are increased
by up to a factor of 2 when these newly observed pygmy resonances are included.
These results lend credence to theoretical predictions of enhanced reaction
rates due to such pygmy resonances and hence are important for a better
understanding of r-process nucleosynthesis.
