ABSTRACT: The authors have obser+~ed that when a shock�wave is accelexated betwe~;n
straight conductors in a plasmas ithe plasmaids are emitted with different veloci~� .
ties, �~hus indicating a splitting of the shock wave. S;fnce this `
similar to that occurring in a Ma~~shall et the author+s att phenomenon is ;
~ , empt to attribute it
to a similarity in �the configurat~ton of the 3.nternal
ma~;netie field in both case~c.
~JUst ass in the MarshaLt tube the ~eagnetie field at the middle conductor is larger
than at the ~aeket, so is the magz~stic field inside stxi~ight conductors much lar~;e,r
at the two conductors than in the middle between them. ~e authors therefore ex-~
press the opinion that one of the main causes of the splitting of thy.shack gave
