A Detailed analysis and Monte Carlo simulation of the neutron lifetime experiment

We performed a detailed analysis and the Monte Carlo simulation of the neutron lifetime experiment (Phys. Lett. B <b>483</b>, 15 (2000)) because of the strong disagreement by 5.6 standard deviations between the results of this experiment and our experiment [1]. We found a few effects which were not taken into account in the experiment [3]. The possible correction is $-5.5$ s with uncertainty of 2.4 s which comes from initial data knowledge. We assume that after taking into account this correction the result of work [3] for neutron lifetime $885.4\pm 0.9_{\rm stat}\pm 0.4_{\rm syst}\,$s could be corrected to $879.9\pm0.9_{\rm stat }\pm 2.4_{\rm syst}$ s.
