To Shell Model, or Not to Shell Model, That Is the Question

چکیده
The present review takes steps from the domain of shell model into open nuclei. question posed in title is to dramatize how far approaches, i.e., many nucleons occupying independent-particle configurations and interacting through two-body forces (a configuration interaction problem) can provide a description nuclei as one explores structure observed where neither proton nor neutron numbers match closed shells. Features doubly singly adjacent are sketched, together with roles played by seniority, shape coexistence, triaxial shapes particle–core coupling organizing data. An illuminating step taken here detailed study reduced transition rates, B(E2;21+→01+), plus or minus pair identical nucleons, confrontation between such data state-of-the-art calculations: this amounts effective charge problem. results raise questions point need for much further work. Some guidance on criteria sharpening division that deformation-based descriptions provided. paper sketch promising direction terms algebraic embodied symplectic model.

To scavenge or not to scavenge: that is the question.
Analysis of a series of diffraction data sets measured from four native as well as four nicotinic acid-soaked crystals of trypsin at 100 K shows a high variability in radiation-sensitivity among individual crystals for both nicotinic acid-soaked and native crystals. The level of radiation-sensitivity and the extent of its variability is statistically indistinguishable between the two conditions...

In 1993 Eugene Harris, a well-known biostatistician at the NIH, wrote an editorial for Clinical Chemistry regarding the use of P values vs confidence intervals in the evaluation of scientific data (1 ). This has long been a contentious topic in the scientific world and one with which each new generation of scientists has had to grapple on the basis of arguments advanced for the use of various s...
