Abstract
We discuss the numerical problems in the calculation of the hypertriton electroproduction cross section. We found that the accuracy of the calculation could still be maintained if we used at least four lowest partial waves of the nuclear wave functions. We also present the cputimes required to calculate the cross sections. We found that the cputime could be reduced by a factor of 60 if we used these specific partial waves, whereas the deviation of calculated cross section from the full calculation is less than 4�We conclude that in view of the present experimental error bars future investigations could just use these lowest partial waves.
