We elucidate the decay amplitude of <math><mi>\u03a6</mi><mo>\u2192</mo><mi>\u03d5</mi><mi>\u03d5</mi></math> from this. In such an amplitude of wave packets, there are in and out time boundaries for the initial <math><mi>\u03a6</mi></math> and final <math><mi>\u03d5</mi><mi>\u03d5</mi></math> configurations, respectively. In this paper, we prove that the effect of the in time boundary of <math><mi>\u03a6</mi><mo>\u2192</mo><mi>\u03d5</mi><mi>\u03d5</mi></math> emerges from <math><mi>\u03d5</mi><mi>\u03d5</mi><mo>\u2192</mo><mi>\u03a6</mi><mo>\u2192</mo><mi>\u03d5</mi><mi>\u03d5</mi></math> without assuming any time boundary a priori. This effect has been overlooked in the standard plane-wave formulation and can exhibit distinct phenomena in wide areas of science. We confirm the result in different integration orders. The result is also interpreted as a Stokes phenomenon in the Lefschetz-thimble decomposition."
