According to the Rayleigh criterion, resolution is possible when the minimum angular separation is. … WebApr 14, 2024 · The acceleration of ultrathin targets driven by intense laser pulses induces Rayleigh–Taylor-like instability. Apart from laser and target configurations, we find that electron heating and surface rippling, effects inherent to the interaction process, have an important role in instability evolution and growth.
WebJan 30, 2003 · In the case of an isothermal liquid bridge between circular disks without any axial acceleration, g=0, having cylindrical volume V*=πR 2 L (its interface would then be a right circular cylinder), the well-known Rayleigh stability limit holds. In this case the liquid column becomes unstable when its length is larger than its circumference (L>2πR).
