An Intiative by Sri Chaitanya
a
If kinetic energy of the neutron is less than 20.4 eV collision must be elastic.
b
If kinetic energy of the neutron is less than 20.4 eV collision may be inelastic.
c
Inelastic collision may take place only when initial kinetic energy of neutron is greater than 20.4 eV.
d
Perfectly inelastic collision can not take place.
answer is A.
