14Be(p,n)14B reaction at 69 MeV in inverse kinematics

A Gamow-Teller (GT) transition from the drip-line nucleus 14Be to 14B was studied via the (p,n) reaction in inverse kinematics using a secondary 14Be beam at 69 MeV/nucleon. The invariant mass method is employed to reconstruct the energy spectrum. A peak is observed at an excitation energy of 1.27(2) MeV in 14B, together with bumps at 2.08 and 4.06(5) MeV. The observed forward peaking of the state at 1.27 MeV and a good description for the differential cross section, obtained with a DWBA calculation provide support for the 1+ assignment to this state. By extrapolating the cross section to zero momentum transfer the GT-transition strength is deduced. The value is found to compare well with that reported in a beta-delayed neutron emission study.Comment: 5 pages, 2 figure

Criminal Justice Case Briefs: Significant Cases in Corrections

This concise, invaluable volume is comprehensive in its treatment of corrections law, covering all of the major cases in the area. It features a list of cases, in alphabetical order and grouped by topic; briefs of each case, arranged by topic; a short introduction to each topic, which places the cases into a larger context; and a helpful index. This text is one of three books in the Criminal Justice Case Briefs series, each of which provides a summary and analysis of leading cases in a particular area of criminal justice: criminal procedure law, corrections law, or juvenile law. Easily accessible to undergraduates, each volume has the same basic outline and format, which is neither exclusively casebook nor textbook. The purely casebook approach is not always appropriate for undergraduates, whose primary focus is learning the law, not how to think like a lawyer. Therefore, these books present briefs (or summaries) of the opinions, along with analyses and explanations, instead of the actual opinions themselves. This allows instructors to use the books as either supplements or as main, stand-alone texts. The volumes also include less background and extraneous material than most textbooks; the cases are presented in a context, with relevant commentary, which allows students to better understand the significance of the legal holdings, explains the Court\u27s holdings, and places each case in context with the Court\u27s other decisions.https://scholarworks.boisestate.edu/fac_books/1187/thumbnail.jp

A neutron based vehicle-borne improvised explosive device detection system

Vehicle-borne improvised explosive devices pose significant risk to government facilities, economic centers and the general public. The detonation of large-scale explosive devices is a worldwide phenomenon. Checkpoint operations currently call for a manual search of vehicles, putting personnel at high risk. We have built a prototype, remotely controlled system to non-intrusively and non-destructively detect explosives with a vehicle inspection time of between 2 and 5 min. The system utilizes a neutron generator and high-purity germanium (HPGe) detectors housed in moving components that scan the entire vehicle and allow for a single location rescan. The neutron generator operates at similar to 10(8) neutrons per second resulting in extremely small induced radiation levels and low exposure to possible stowaways. A control software operator interface is fully automated for remote operation of the hardware components and execution of the data analysis and threat algorithm with no operator intervention. Studies have been completed to characterize the performance of the system as a function of the weight of explosive within a complete set of vehicles. The underlying physical concepts of the system development are presented. (c) 2007 Elsevier B.V. All rights reserved
