Abstract

The first acceleration measurements are reported for negative ions in bulk superfluid 4He. Data recorded at 70 mK, 25 bars for electric fields in the range 80 < E < 150 V are consistent with an ionic dispersion relation identical to that of a free particle with mass (87 ± 5)m4, where m4 is the 4He atomic mass.
