Title: Reply to Janoschek et al.: The excited δ-phase of plutonium

In a recent PNAS paper (1) we discuss the anomalous temperature dependence of the elasticity in δ-plutonium (δ-Pu) in terms of a first-principles model that includes multiple energy configurations attributed to spin fluctuations. We think it is obvious that conclusions from the earlier experimental report (6) are inconsistent with the latest neutron-scattering experiments (4), as well as comments made in Janoschek et al. (2)
