METHOD      The branching ratio was obtained from the             20095  1   12 
            two peaks corresponding to the two different q-values 20095  1   13

            fragments in the counter gas.                         20095  1   15

ANALYSIS    The branching ratio is calculated from the            20095  1   17 
            quotient between the sums of the number of pulses in  20095  1   18
