SP-345 Evolution of the Solar
System
FIGURE 21.8.7.- Velocity retardation
to near the critical value in the Danielsson experiment. Plasma
deceleration with depth of penetration z in a neutral gas cloud
of helium is shown. The front of the cloud is located at
z = -5
cm, and the center, at z
= 0 cm. The plasma undergoes
deceleration from the impinging velocity v0 to near the
critical velocity vcrit of helium.
Data for two values of the magnetic field B are shown. (From
Danielsson, 1969b.)
