New limits on the ordered moments in alpha-Pu and Ga-stabilized delta-Pu
We present the first muon spin relaxation measurements ever performed on
elemental Pu, and set the most stringent upper limits to date on the magnitude
of the ordered moment in alpha-Pu and delta-stabilized Pu (alloyed with 4.3 at.
% Ga). Assuming a nominal hyperfine coupling field of 1 kOe per Bohr magneton
we set an upper limit of 0.001 Bohr magnetons for both materials at T = 4 K.Comment: 4 pages, 3 figures. Submitted to 10th International Conference on

Size Effects in Angle-Resolved Photoelectron Spectroscopy of Free Rare-Gas Clusters
The photoionization of free Xe clusters is investigated by angle-resolved time-of-flight photoelectron spectroscopy. The measurements probe the evolution of the photoelectron angular distribution parameter as a function of photon energy and cluster size. While the overall photon-energy-dependent behavior of the photoelectrons from the clusters is very similar to that of the free atoms, distinct differences in the angular distribution point at cluster-size-dependent effects. Multiple scattering calculations trace their origin to elastic photoelectron scattering
Is American Public Administration Detached From Historical Context?: On the Nature of Time and the Need to Understand It in Government and Its Study
The study of public administration pays little attention to history. Most publications are focused on current problems (the present) and desired solutions (the future) and are concerned mainly with organizational structure (a substantive issue) and output targets (an aggregative issue that involves measures of both individual performance and organizational productivity/services). There is much less consideration of how public administration (i.e., organization, policy, the study, etc.) unfolds over time. History, and so administrative history, is regarded as a “past” that can be recorded for its own sake but has little relevance to contemporary challenges. This view of history is the product of a diminished and anemic sense of time, resulting from organizing the past as a series of events that inexorably lead up to the present in a linear fashion. To improve the understanding of government’s role and position in society, public administration scholarship needs to reacquaint itself with the nature of time.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline
