Research Projects
Research on the “Bentley atom” model to visually convey electron configuration and behavior for SPDF sub-shells other than by probability clouds. All previous atomic models including Quantum Electrodynamic theory fail to produce accurate energy values for atoms larger than hydrogen.
For a decade since 2010 to encourage solar research at PV, C. Bentley found success in solving dome maintenance problems, such as dome rotation shut-downs from motor stoppage, motor-gear to track misalignment from loose and bent track, relay-contacts corrosion, telescope array east-west, as well as north-south, panning stoppage from burned relay contacts, primary and secondary telescope alignment problems, vacuum system oil contamination problems, telescope vacuum-leak detection of problem from cracked primary telescope lens, solved long-standing primary telescope exit-window contamination problem. Worked on CCD camera and replacement camera serial port and camera in telescope alignment, and the like.
Recently worked with Dr. Cifja in publishing exact solutions to some long-standing problems concerning plasma confinement, etc.
