A Jersey City City Councilman has used his opposition to the controversial Spectra Energy natural-gas pipeline to vote against granting the Houston energy giant an easement to place the pipe ...

As a result each produces photons with different energy and so the line spectra for different elements will be different. This means that line spectra can be used to identify elements. Continuous ...

the photons with the same energy as the energy gaps in the atoms can be absorbed. This causes an absorption spectra, as shown below. Because the energy levels are the same, the lines in the ...

This supplement is an update of Technical Report Series No. 318, Compendium of Neutron Spectra and Detector Responses for Radiation Protection Purposes (1990), that takes into account the major ...
