Nuclear reaction Common light particles are often abbreviated in this shorthand, typically p for proton, n for neutron, d for deuteron, α representing an alpha particle or helium-4, β for beta particle or electron, γ for gamma photon, etc. The reaction above would be written as Li-6(d,α)α. In 1919, Ernest Rutherford was able to accomplish transmutation of nitrogen into oxygen at the University of Manchester, using alpha particles directed at nitrogen N + α → O + p. This was the first observation of an induced nuclear reaction, that is, a reaction in which particles from one decay are used to transform
Pirkko Eskola using the Heavy Ion Linear Accelerator, bombarding a target of californium-249 with nitrogen nuclei. There was debate between Russia and America over who first discovered of Rutherfordium. Erkola studied the alpha decay of Nobelium 255 and 257. She went on to work on beta-unstable Alpha particle emitting nuclei. Using Alpha-particle spectroscopy she studied lawrencium isotopes 255 - 260 and Mendelevium isotopes 248 - 252. Her husband, Kari Eskola, was a professor of physics at the University of Helsinki. She went on to have a career in science education. She was an editor of the Finnish Physical Society journal "Physica Fennica".
