摘要
The result of the neutron lifetime tau(n) measurement in the ultra-cold neutron gravitational trap experiment is given. The experimental errors are analyzed. The statistical error of determining the keeping times is shown to give the main contribution. According to the results of the trap oxygen coating measurements tau(n) is 888.4+/-3.1stat+/-1.1syst s. Since the systematic errors are due to the large amount of independent factors, the final result can be represented as tau(n)=888.4+/-3.3 s.
