QUESTION
The reaction 11B( (alpha sign) ,n)14N is found to be exothermic, producing 0.157 MeV.
The reaction 11B(α (alpha sign) ,n)14N is found to be exothermic, producing 0.157
MeV. Based on this information, calculate the atomic weight in atomic mass units (u) of
a neutron to six decimal places. (Assume that the atomic weight of an alpha-particle is
equal to that of a neutral 4He2 atom.)
