Neutron Decay 4 On their own, neutrons are unstable particles with a half-life of 618 s when at rest. They decay into a proton, an electron and an electron antineutrino. Half-life is the time that it takes half of a collection of unstable particles to decay. a- The highest energy neutrons produced in a nuclear reactor are traveling at about %15 of the speed of light, About how many seconds is longer in this half - life for these neutrons?...

Given data: Ln2=0.693, 1Ci=3,7.1010 des/s 140Ba radionuclide with half-life Tp=306 hours decays to its daughter 140La with a half-life of Td=40.3 hours and to stable granddaughter 140Ce. The scheme of the decay is illustrated as follows: 140Ba → 140La → 140Ce The parent, 140Ba, has an initial activity of A0=5mCi. The initial number of nuclei (at t=0) of the daughter 140La is N0 = 0, and tm is the time when the daughter activity reaches its maximum value.  The equations of...
