    Tritium is an isotope of hydrogen whose nucleus Triton contains 2 neutrons and 1 proton. Free neutron decay into p+bare+barv . If one of the neutrons in Triton decays. It would transform into He^3 nucleus. This does not happen. This is because.

    A proton, a neutron, an electron and alpha -particle have the same energy. Then their de-Broglie wavelengths compare is

    Consider the decay of the free neutron at rest: n = p + e^- . Show that the two-body decay of this type must necessarily give an electron of fixed energy and, therefore, cannot account for the observed continuous energy distribution in the beta decay of a neutron or a nucleus.

    A neutron, a proton, an electron and an alpha particle enter a region of constant magnetic field with equal velocities. The magnetic field is along the inward normal to the plane of paper. The tracks of the particles are labelled in Fig. SAQ 11. which of the tracks show the path of the electron and alpha-particles ?

    Obtain the de-Broglie wavelength associated with thermal neutrons at room temperature (27^@C) . Hence explain why a fast neutron beam needs to be thermalized with the environment before it can be used for neutron diffraction experiments.

    Heavy stable nuclie have more neutrons than protons. This is because of the fact that
