Parity-Dependence in the Nuclear Level Density [PDF]
, 2004 Astrophysical reaction rates are sensitive to the parity distribution at low excitation energies. We combine a formula for the energy-dependent parity distribution with a microscopic-macroscopic nuclear level density.

Parity Dependence of Nuclear Level Densities [PDF]
Physical Review Letters, 2000 A simple formula for the ratio of the number of odd- and even-parity states as a function of temperature is derived. This formula is used to calculate the ratio of level densities of opposite parities as a function of excitation energy. We test the formula with quantum Monte Carlo shell model calculations in the $(pf+g_{9/2})$-shell.

Power-law intensity distribution in $\gamma$-decay cascades -- Nuclear Structure as a Scale-Free Random Network [PDF]
, 2020 By modeling the transition paths of the nuclear $\gamma$-decay cascade using a scale-free random network, we uncover a universal power-law distribution of $\gamma$-ray intensity $\rho_I(I) \propto I^{-2}$, with $I$ the $\gamma$-ray intensity of each ...

New treatment of the chiral SU(3) quark mean field model [PDF]
, 2004 We perform a study of infinite hadronic matter, finite nuclei and hypernuclei with an improved method of calculating the effective baryon mass. A detailed study of the predictions of the model is made in comparison with the available data and the level ...
