摘要：

The neutron lifetime n has been measured by counting decay protons stored in a Penning trap whose magnetic axis coincided with a neutron-beam axis. The result of the measurement is n=893.6±5.3 s, which agrees well with the value predicted by precise measurements of the -decay asymmetry parameter A and the standard model. © 1990 The American Physical Society.
