A flipped classroom provides students with course content in the form of videos, readings, and/or simulations that they complete during the time traditionally used for homework assignments while in-class time is devoted to hands-on group learning activities. Project BoxSand is gathering quantitative data on how students in a flipped classroom,...
The N=88 isotones lie on the onset of nuclear deformation and have a complicated nuclear structure. To better understand this region, the nuclear levels of ¹⁵⁰Sm were studied in three different β decay experiments. De-populating γ-rays were measured using the 8π spectrometer, an array of 20 Compton suppressed Ge detectors....
Angular correlations of gamma rays from excited states of ¹⁶⁶Er have been
measured following the β decays of ¹⁶⁶ Ho (Jπ =7-, t 1/2 =1200y, Q= 1854 ke V) and ¹⁶⁶Tm (Jπ = 2+, t 1/2, = 7.7h, Q=3040 keV).
Data was collected using the 8π
spectrometer, an array of...
With the unique conceptual and mathematical backgrounds of every introductory physics student, there is no way to design a rigid curriculum that anticipates and meets every student’s needs. We can employ machine learning to explore the correlations that exist in the voluminous data from educational settings. That is, institutional, gradebook,...
¹⁸⁶Ir gamma transitions are studied via the reaction
Hf (¹⁴N, xn) Au at ¹⁴N beam energy 130 MeV. The beta decay
chain of Au is Au + Pt + Ir + Os. Singles and coincidence
data are from measurements by Ge gamma-ray detectors.
Conversion electrons are measured by Si(Li) detector....
As part of a research program to study the transitional region of N=88
isotones, ¹⁵²Tb was produced by the reaction ¹⁵¹Eu(α,3n)¹⁵²Tb in the 88" cyclotron
located at LBNL. Gamma-ray spectroscopy of the radiation emitted from excited
¹⁵²Gd following the β⁺ decay of ¹⁵²Tb has been performed using an array of...
When a nucleus is in an excited state, it will decay to lower energy by emitting photons. Often there are several intermediate stages in a decay cascade. Occasionally the photons in a cascade will be emitted in coincidence. This will be resolved by the detector not as two distinct photons,...
