1. Energy Levels and Observed Spectral Lines of Neutral and Singly Ionized Titanium, Ti I and Ti II
Series: J. Phys. & Chem. Ref. Data (JPCRD)
Topic: Physics
Published: 1/12/2012
Author: Edward Barry Saloman
Abstract: The energy levels and observed spectral lines of neutral and singly ionized titanium atoms have been compiled. Tables of energy levels and spectral lines are generated for each stage. Experimental g-factors and leading percentages are included when ...

4. A Green Laser Pointer Hazard
Series: Technical Note (NIST TN)
Report Number: 1668
Topic: Physics
Published: 8/2/2010
Authors: Jemellie Galang, Alessandro Restelli, Edward Walter Hagley, Charles W Clark
Abstract: An inexpensive green laser pointer was found to emit 20 mW of infrared radiation during normal use. This is potentially a serious hazard that would not be noticed by most users of such pointers. We find that the problem derives from an unsafe desig ...
