Calculation

tn: Neutron time of flight

tɣ: Gamma time of flight

d: Distance between detector and target.

d for polarized case: dpol = 91.25 inches = 231.775 cm


tn-tɣ=l/v-l/c=l(1/v-1/c)

=> v=1/[(tn-tɣ)/l-1/c]


βn=v/c

ɣn=(1-βn2)-1/2

Etot=Mnɣnc2

Ek=Etot-Mnc2

Data

Polarized

Unpolarized to Top Detector

Unpolarized to Side Detector
