Query: Constraining the $^{22}$Ne($\alpha$,$\gamma$)$^{26}$Mg and
  $^{22}$Ne($\alpha$,n)$^{25}$Mg reaction rates using sub-Coulomb
  $\alpha$-transfer reactions   The $^{22}$Ne($\alpha$,$\gamma$)$^{26}$Mg and $^{22}$Ne($\alpha$,n)$^{25}$Mg
reactions play an important role in astrophysics because they have significant
influence on the neutron flux during the weak branch of the s-process. We
constrain the astrophysical rates for these reactions by measuring partial
$\alpha$-widths of resonances in $^{26}$Mg located in the Gamow window for the
$^{22}$Ne+$\alpha$ capture. These resonances were populated using
$^{22}$Ne($^6$Li,d)$^{26}$Mg and $^{22}$Ne($^7$Li,t)$^{26}$Mg reactions at
energies near the Coulomb barrier. At these low energies $\alpha$-transfer
reactions favor population of low spin states and the extracted partial
$\alpha$-widths for the observed resonances exhibit only minor dependence on
the model parameters. The astrophysical rates for both the
$^{22}$Ne($\alpha$,$\gamma$)$^{26}$Mg and the $^{22}$Ne($\alpha$,n)$^{25}$Mg
reactions are shown to be significantly different than the previously suggested
values.
