Board exams are around the corner and it is time for the students to revise the syllabus and start practising the questions ...

In fact, they're identical to a few parts in ten billion. This is not, in fact, very surprising, as there are particle-decay experiments that place a slightly more stringent constraint on possible ...

From the discovery of gravity to the first mission to defend Earth from an asteroid, here are the most important physics ...

It will also provide a valuable summary and reference for researchers already working in electron scattering and other areas of nuclear and particle physics. This text has been reissued as an Open ...

In neutron scattering experiments, instruments count the scattered neutrons as a function of wave vector Q, which depends on the scattering angle θ and wavelength λ. For elastic scattering – i.e., ...

It produces an alpha particle (or Helium-4 nucleus) and a neutron, and releases 17.6 megaelectron volt (MeV) of energy in the form of kinetic energy of the products (3.5 MeV to alpha particle and 14.1 ...

An unstable nucleus can emit a ‘package’ of two protons and two neutrons, called an alpha particle, to become more stable. Alpha radiation is made up of a stream of alpha particles emitted ...

Particle physics is a type of physics which looks at particles which make up matter and radiation. Also known as high energy physics, particle physics explores the smallest detectable particles ...

The thicker the substance, the more the radiation is absorbed. Alpha, beta and gamma radiations penetrate materials in different ways. Alpha radiation is the least penetrating. It can be stopped ...
