Scientific paper

During the approach of Pioneer 7 to a distance of 12.1×106km from the nucleus of comet P/Halley on March 20, 1986, features were observed in plasma analyzer data that the authors interpret as He+ produced by charge exchange of solar wind He++ with neutral cometary material. The maximum flux of the He+ was observed several hours after the closest approach of the spacecraft of the nucleus, and is unexpectedly large. Remarkable large discontinuous flux changes were also observed.
