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.

d for unpolarized top detector: dunpol_top=96.25 inches = 244.745 cm.

d for unpolarized side detector: dunpol_side=91.39 inches = 232.131 cm.


tn-tɣ=d/v-d/c=d(1/v-1/c)

=> v=1/[(tn-tɣ)/d-1/c]


βn=v/c

ɣn=(1-βn2)-1/2

Etot=Mnɣnc2

Ek=Etot-Mnc2
