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
