what were her researches?
Their experiments identified both the positron and the neutron, replaced John Dalton's model of atoms as solid spherical particles, were the first to calculate the accurate mass of the neutron.
Irène Joliot-Curie
 Experiments were done using gamma rays to identify the positron. Though their experiments identified both the positron and the neutron, they failed to interpret the significance of the results and the discoveries were later claimed by Carl David Anderson and James Chadwick respectively. These discoveries would have secured greatness indeed, as together with J. J. Thomson's discovery of the electron in 1897, they finally replaced John Dalton's model of atoms as solid spherical particles.

However, in 1933, Joliot-Curie and her husband were the first to calculate the accurate mass of the neutron. The Joliot-Curies continued trying to get their name into the scientific community; in doing so they developed a new theory from an interesting experiment they conducted. During an experiment bombarding aluminium with alpha rays, they discovered that only protons were detected. Based on the undetectable electron and positron pair, they proposed that the protons changed into neutrons and positro
who used a nuclear accelerator to strike neutrons into the nucleus to start a nuclear chain reaction Frédéric and Irène Joliot-Curie. would nuclear power help to extend lifetime of a plant? Yes, There is a research into Light water reactor sustainability. how were the wastes disposed? Waste is mainly stored at individual reactor sites and there are over 430 locations around the world. does it produce electricity? Yes, Nuclear fission power stations provided 11% of the world's electricity. where are the power stations located? UNANSWERABLE how does it support the economy? Comparison with other power generation methods is strongly dependent on assumptions about construction timescales and capital financing for nuclear plants as well as the future costs of fossil fuels and renewables as well as for energy storage solutions for intermittent power sources. what is the profession of irene joliot mentioned above? She was a French chemist, physicist, and a politician of Polish ancestry.

Irène Joliot-Curie [SEP] Research
As she neared the end of her doctorate in 1924, Irène Curie was asked to teach the precision laboratory techniques required for radiochemical research to the young chemical engineer Frédéric Joliot, whom she would later wed. From 1928 Joliot-Curie and her husband Frédéric combined their research efforts on the study of atomic nuclei. In 1932, Joliot-Curie and her husband Frédéric had full access to Marie's polonium. Experiments were done using gamma rays to identify the positron. Though their experiments identified both the positron and the neutron, they failed to interpret the significance of the results and the discoveries were later claimed by Carl David Anderson and James Chadwick respectively.
