Irene Joliot-Curie independent hard-work mother The farther the experiment is from theory, the closer it is to the Nobel Prize. Irene Joliot-Curie nobel theory science Each emission of an alpha or beta ray accompanies the transmutation of an atom; the energy communicated to these rays comes from inside the atom. Irene Joliot-Curie alpha inside rays energy We have shown that it is possible to create a radioactivity characterized by the emission of positive or negative electrons in boron and magnesium by bombardment with alpha rays. Irene Joliot-Curie possible create positive negative The time necessary for the disappearance of half the atoms, called the half-life, is a fundamental characteristic of each radio-element; according to the substance, the value of the half-life varies between a fraction of a second and millions of years. Irene Joliot-Curie value half time years It was at the beginning of 1934 while working on the emission of these positive electrons that we noticed a fundamental difference between that transmutation and all the others so far produced; all the reactions of nuclear chemistry induced were instantaneous phenomena, explosions.
