Additional neutron lifetime result obtained from ultracold-neutron storage experiments
It is shown by an analysis of the results of neutron lifetime measurements in JETP Lett. 57, 82 (1993) that one of the corrections—the correction for leakage from the slit in the gate closing off the vessel storing ultracold neutrons—must be positive. After this sign is reversed and the errors are averaged over the temperatures, the neutron lifetime is found to be 7^=887.6+2.3. Although this result is in better agreement with the value currently adopted for τ β, it is unreliable because the scatter in the values obtained (the possible source for this scatter is not discussed) is almost two orders of magnitude greater than the systematic error indicated by the authors. © 1995 American Institute of Physics.
