Query: A high-resolution study of levels in the astrophysically important
  nucleus $^{26}$Mg and resulting updated level assignments   The $^{22}$Ne($\alpha,n$)$^{25}$Mg reaction is an important source of
neutrons for the s-process. Due to the difficulty in directly measuring the
cross section of this reaction and the competing
$^{22}$Ne($\alpha,\gamma$)$^{26}$Mg reaction, indirect methods are frequently
used to try to instead calculate the relevant reaction rates. Uncertainty,
however, persists in the number and properties of the pertinent excited states
of $^{26}$Mg.
  In this paper, the results of proton and deuteron scattering from $^{26}$Mg
are presented, giving a list of levels in $^{26}$Mg. In addition, level
assignments in $^{26}$Mg are discussed, including some possible changes to the
previously accepted assignments in $^{26}$Mg.
