\Gamma_L(m;m_0,\Gamma_0)=\Gamma_0 \frac{m_0}{m} \frac{q}{q_0} \frac{F^2_L(q)}{F^2_L(q_0)}
\Gamma_L(m;m_0,\Gamma_0)=\Gamma_0 \frac{m_0}{m} \frac{q}{q_0} \frac{F^2_L(q)}{F^2_L(q_0)}

where ''q'' is the breakup momentum of the daughter particles and ''q<sub>0</sub>'' is the same, evaluated at ''m<sub>0</sub>''.
where ''q'' is the breakup momentum of the daughter particles in the rest frame of the parent particle, and ''q<sub>0</sub>'' is the same, evaluated at ''m<sub>0</sub>''.

q(m) = \sqrt{\left(\frac{m^2+m_1^2-m_2^2}{2m}\right)^2-m_1^2}

The functions <math>F_L(q)</math> are the angular momentum barrier factors that are given in the literature. ''The first few of these barrier factors should be listed explicitly here.''
