New formulas for the (−2) moment of the photoabsorption cross section, σ−2
(American Physical Society, 2015)
Two new formulas for the (−2) moment of the photoabsorption cross section, σ−2, have been determined,
respectively, from the 1988 photoneutron evaluation of Dietrich and Berman and a mass-dependent symmetry

Nonlinear galactic dynamos and the magnetic pitch angle
(American Astronomical Society, 2015)
Pitch angles p of the large-scale magnetic fields B of spiral galaxies have previously been inferred from
observations to be systematically larger in magnitude than predicted by standard mean-field dynamo theory. ...
