Measurement of neutron lifetime through storage of ultracold neutrons
Kosvintsev Yu. Yu., Morozov V. I., Terekhov G. I.
The lifetime of the neutron has been measured by a method of storage of ultracold neutrons in a cooled, hermetically sealed aluminum vessel. The result is 903 + 13 s. Preliminary data from measurements of the neutron lifetime during the storage of ultracold neutrons in a vessel with walls made of heavy-water ice are reported.
