  • The year 1932 is usually considered the annus mirabilis of nuclear physics. In that year, in Cambridge, the neutron was discovered by J. Chadwick [1] by bombarding beryllium and boron with the alpha particles from polonium; in the USA, the positive electron was discovered by Anderson in cosmic rays; and the heavy hydrogen (the deuterium or hydrogen of atomic weight 2: whose nucleus is called deuteron) was found by H. Urey. Also in the USA, J. Cockcroft and E. Walton completed their particle… CONTINUE READING
