“…Forming the square of Eqs. 5*13 and 5.1^ and differentiating with respect to time gives ft [(P y ) 2 + (P z -qB y)2 J +^( 2q r. rp) = o ,(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15) which implies ^ [Py + (P z -q B y) 2 ] + q (J>(y,z) = C , (p.lb)where C ■ constant.iThe left-hand side of this last equation is simply H as given by Eq. 5«10« Thus for a conservative system H (y, z, p .…”
