The Z=82 shell closure in neutron-deficient Pb isotopes [PDF]

open access: yes, 2001
Recent mass measurements show a substantial weakening of the binding energy difference delta_{2p} (Z,N) = E(Z-2,N) - 2 E(Z,N) + E(Z+2,N) in the neutron-deficient Pb isotopes. As delta_{2p} is often attributed to the size of the proton magic gap, it might

Rapid directional alignment of velocity and magnetic field in magnetohydrodynamic turbulence [PDF]

open access: yes, 2007
We show that local directional alignment of the velocity and magnetic field fluctuations occurs rapidly in magnetohydrodynamics for a variety of parameters. This is observed both in direct numerical simulations and in solar wind data.
