Octupole response and stability of spherical shape in heavy nuclei [PDF]

, 2003
The isoscalar octupole response of a heavy spherical nucleus is analyzed in a semiclassical model based on the linearized Vlasov equation. The octupole strength function is evaluated with different degrees of approximation.

On the stabilization of ion sputtered surfaces [PDF]

, 2007
The classical theory of ion beam sputtering predicts the instability of a flat surface to uniform ion irradiation at any incidence angle. We relax the assumption of the classical theory that the average surface erosion rate is determined by a Gaussian ...
