Meitner–Hupfeld effect
Encyclopedia
The Meitner–Hupfeld effect is an anomalously large scattering of Gamma rays by heavy elements
. Later on, the Meitner–Hupfeld effect was explained by a broad theory from which evolved the Standard Model, a theory for explaining the structure of the atomic nucleus
. The anomalous gamma-ray behavior was eventually ascribed to electron–positron pair production and annihilation.
Although Professor Meitner
was recognized for her work, Dr. Hupfeld
is usually ignored, and little or no account of his life exists.
Chemical element
A chemical element is a pure chemical substance consisting of one type of atom distinguished by its atomic number, which is the number of protons in its nucleus. Familiar examples of elements include carbon, oxygen, aluminum, iron, copper, gold, mercury, and lead.As of November 2011, 118 elements...

Atomic nucleus
The nucleus is the very dense region consisting of protons and neutrons at the center of an atom. It was discovered in 1911, as a result of Ernest Rutherford's interpretation of the famous 1909 Rutherford experiment performed by Hans Geiger and Ernest Marsden, under the direction of Rutherford. The...
