On a Diffuse Reflection of the α – Particles

  title={On a Diffuse Reflection of the $\alpha$ – Particles},
  author={Ernest Marsden},
When β-particles fall on a plate, a strong radiation emerges from the same side of the plate as that on which the β-particles fall. This radiation is regarded by many observers as a secondary radiation, but more recent experiments seem to show that it consists mainly of primary β-particles, which have been scattered inside the material to such an extent that emerge again at the same side of the plate1. For α-particles a similar effect has not previously been observed, and is perhaps not to be… Expand

Nickel-Hydrogen Cold Fusion by Intermediate Rydberg State of Hydrogen: Selection of the Isotopes for Energy Optimization and Radioactive Waste Minimization
The main objection against cold fusion is based on the theoretical understanding that the Coulomb barrier of the very small nucleus is extremely strong. The size of the atomic nucleus is determinedExpand
A shadow of the repulsive Rutherford scattering in the fixed-target and the center-of-mass frame
The paper explores the shadow of the repulsive Rutherford scattering - the portion of space entirely shielded from admitting any particle trajectory. The geometric properties of the projectile shadowExpand
Interactions of Single Particle with Organic Matters: A Facile Bottom-Up Approach to Low Dimensional Nanostructures
A particle induces a pack of chemical reactions in nanospace: chemical reactions confined into extremely small space provide an ultimate technique for the nanofabrication of organic matter with aExpand
Scientific Revolution in the Development of the Rutherford-Bohr Model of the Atom
1897-1914 was a period of rapid scientific progress with respect to atomic modeling. In just seventeen years Thomson, Rutherford, and Bohr would transform the world’s conception of the atom from aExpand
Photonic Rutherford scattering: A classical and quantum mechanical analogy in ray and wave optics
Using Fermat's least-optical-path principle, the family of ray trajectories through a special (but common) type of a gradient refractive index lens n(r)=n0+ΔnR/r is solved analytically. The solutionExpand
Probing the transverse spin of quarks in deep inelastic scattering
To identify some way to measure the quark transversity, this thesis analyzes one-particle and two-particle inclusive deep inelastic scattering, where one and two of the outgoing hadrons are detectedExpand
Self-consistent conversion of a viscous fluid to particles
Comparison of hydrodynamic and "hybrid" hydrodynamics+transport calculations to heavy-ion data inevitably requires the conversion of the fluid to particles. For dissipative fluids the conversion isExpand
To implemet the Gravitational constant and the Avogadro number in atomic, nuclear and particle physics
It is very clear that, to unify 2 interactions if 5 dimensions are required, for unifying 4 interactions 10 dimensions are required. For 3+1 dimensions if there exists 4 (observed) interactions, forExpand
Atomic Modeling in the Early 20th Century: 1904-1913
The early years of the 20th century was a time when great strides were made in understanding the nature of atoms, which had been theretofore thought of as indivisible components of matter, with noExpand
Mass measurements of neutron-rich strontium and rubidium isotopes in the A ≈ 100 and development of an electrospray ionization ion source
An extension of the atomic mass surface in the region A ≈ 100 is performed via massmeasurements of the 100-102Sr and 100-102Rb isotopes with the ion-trap mass spectrometer ISOLTRAPat CERN-ISOLDE. TheExpand
