Abstract A beam-foil measurement of the meanlife of the 1s 3p 1 P level in He I has been made and yields the value 1.7225±0.0046 ns. The measurement was made with standard beam-foil techniques and equipment, but special attention was devoted to minimizing sources of uncertainty. The precision far exceeds that of previous beam-foil meanlife measurements and demonstrates that the beam-foil technique is capable of high precision and is competitive with and more flexible than methods such as resonant laser excitation.
