A 21 st century Rutherford experiment

چکیده

In 1909, Hans Geiger and Ernest Marsden [1] reported on the strange behavior of α particles scattered by a gold foil. They observed a wide angular distribution that could not be explained by Thompson’s picture of an atom consisting of “a number N of negatively charged corpuscles, accompanied by an equal number of positive electricity uniformly distributed throughout a sphere” [2]. Ernest Rutherford explained these observations by proposing a small positively charged nucleus in the center of the atom, drawing the first conclusions on the structure of the atomic nucleus [3]. On the basis of this assumption he developed a formula that precisely describes the elastic scattering in ion-ion collisions and set the starting point for a long history of reaction mechanism studies.

21st Century Regionalism: Filling the gap between 21st century trade and 20th century trade rules

This paper weaves several sets of facts into an argument that: 1) today’s trade is radically more complex, involving a “trade-investment-service nexus”, 2) this 21 st century trade demanded deeper disciplines which were supplied by “21 st century regionalism” while the WTO was otherwise occupied, and 3) 21 st century regionalism has quite different implications for the world trading system than...

Dynamical Downscaling Projections of 21 st Century Atlantic Hurricane 1 Activity : CMIP 3 and CMIP 5 Model - based Scenarios

20 Twenty-first century projections of Atlantic climate change are downscaled to explore the 21 robustness of potential changes in hurricane activity. Multi-model ensembles using the 22 CMIP3/A1B (Late 21 st century) and CMIP5/RCP4.5 (Early and Late 21 st century) scenarios are 23 examined. Ten individual CMIP3 models are downscaled to assess the spread of results among 24 the CMIP3 (but not th...

Detection of High-Angle Alpha Particle Scattering through Gold Foil

In the beginning of the 20th century, physicists had begun to determine the structure of atoms. J.J. Thomson had discovered the presence of electrons negatively charged particles with a mass much less than the overall mass of the electron using cathode rays[1]. Thomson further hypothesized that the full structure of the atom consisted of electrons surrounded by a ”soup” of positive charge. This...
