What is minimum possible temperature a body can have ? Given its value in Kelvin and Celsius scale.

The beta -decay process, discovered around 1900 , is basically the decay of a neutron (n) , In the laboratory, a proton (p) and an electron (e^(-)) are observed as the decay products of the neutron. Therefore, considering the decay of a neutron as a tro-body dcay process, it was observed that the electron kinetic energy has a continuous spectrum. Considering a three-body decay process i.e., n rarr p + e^(-)+overset(-)v_(e ) , around 1930 , Pauli explained the observed electron energy spectrum. Assuming the anti-neutrino (overset(-)V_(e )) to be massless and possessing negligible energy, and neutron to be at rest, momentum and energy conservation principles are applied. From this calculation, the maximum kinetic energy of the electron is 0.8xx10^(6)eV . The kinetic energy carried by the proton is only the recoil energy. What is the maximum energy of the anti-neutrino?

A free hydrogen atom in its ground state is at rest. A neutron having kinetic energy k_(0) collides head one with the atom. Assume that mass of both neutron and the atom is same. (a) Find minimum value of k_(0) so that this collision can be inelastic. (b) If k_(0) = 25 eV , find the kinetic energy of neutron after collision if its excites the hydrogen atom to its second excited state. Take ionization energy of hydrogen atom in ground state to be 13.6 eV .

Moderator is used in a nuclear to slow down fast neutrons generated after a fission event in the reactor consider a fast neutron (mass m_(n) ) moving at speed v. The neutron hits a moderator nucleus (Mass M), which is originally static, and gets scattered elastically by 180^(@) (a) Find te rato of kinetic energy of the neutron after and before collision. (b) Show that when Mgtgtm_(n) , neutron does not lose much energy and therefore, a moderator should have a small mass number.
