Write the basic nuclear process of neutron undergoing `beta`-decay . Why is the detection of neutrons found very difficult ?

Write the basic nuclear processes underlying beta^+ and beta^- decays.

Write down the decay scheme of a free neutron

Write the nuclear reaction for the emission of neutron. Indicate e/m value of neutron.

Why is it found experimentally difficult to detect neutrinos in nuclear beta -decay ?

What are thermal neutrons ? Why are neutrons considered as ideal particles for nuclear fission ?

Explain why Rutherford did not mention the present of neutron in the proposed nuclear model of atom?

Consider the fission of ._92^238U by fast neutrons. In one fission event , no neutrons are emitted and the final stable end products, after the beta decay of the primary fragments , are ._58^140Ce and ._44^99Ru . Calculate Q for this fission process. Given , m(._92^238U)=238.05079 u, m(._58^140 Ce) = 139.90543 u m(._44^99Ru) = 98.90594 u, m_n =1.008667 u

Why is neutron used as an ideal particle for bombarding the nucleus of elements in a nuclear reaction ?

In a nuclear reactor , moderators slow down the neutrons which come out in a fission process. The moderator used have light nuclei. Heavy nuclei will not serve the purpose because,
