Abstract: We calculate the complete closed string high energy scattering amplitudesHSA in the Regge regime for arbitrary mass levels. As an application, wededuce the complete ratios among closed string HSA in the fixed angle regime byusing Stirling number identities. These results are in contrast with theincomplete set of closed string HSA in the fixed angle regime calculatedpreviously. The complete forms of the fixed angle amplitudes, and hence theratios, were not calculable previously without the input of zero-norm statecalculation. This is mainly due to the lack of saddle point in the fixed angleclosed string calculation.
