Neutron Capture

In electron capture (radioactive process):

What is meant by electron capture?

In electron capture (radioactive process):

When a slow neutron is captured by U^(235) nucleus nuclear fission takes place, each fission releases an energy of 200 MeV. The number of fissions required to occur (per sec) to produce a power of 1 MW is

When a triton captures a proton, it becomes

A small subatojmic particle was passed through large watger tank conatining Cd . The existence of this particles was inferred when two -gamma- rays were produced and a neutron was captured by Cd . The particle was:

Assertion: In u_(235) fission reaction neutrons are required to be slowed down. Reason: The probability of capture of slow moving neutrons in high for u_(235) .
