... the spherical shape is unstable even without field 2. An earlier estimate1’ 2 of the curvature-elastic modulus is kc= 5 • 10-13 erg. In experiments Fe0 must be small enough to prevent excessive heat in the medium. For f eo = 30 Vcm-1 = 0.1 cgs, r0 — 3-10~4 cm, £w= 80, and c0 = 0 one obtains s2 = 3-1 ...
