<strong>The</strong> Sachs form factors G E (electric) and G M (magnetic) are<br />
more convenient experimentally.<br />
<strong>The</strong> two sets <strong>of</strong> form factors are connected by linear relations<br />
G E = F 1 - τF 2 , G M = F 1 + F 2<br />
or in <strong>the</strong> opposite direction, as we actually measure G E and G M:<br />
F 1 = (G E + τG M)/(1 + τ), F 2 = (G M - G E)/(1 + τ)<br />
with τ=Q 2 /4m p 2<br />
