The energy spectra of neutrons, protons, and α-particles have been measured from the d+59Co and 3He+58Fe reactions leading to the same compound nucleus, 61Ni. The experimental cross sections have been compared to Hauser-Feshbach model calculations using different input level density models. None of them have been found to agree with experiment. It manifests the serious problem with available le...

A method for making realistic estimates of the density of levels in even-even nuclei is presented making use of the Monte Carlo shell model (MCSM). The procedure follows three basic steps: (1) computation of the thermal energy with the MCSM, (2) evaluation of the partition function by integrating the thermal energy, and (3) evaluating the level density by performing the inverse Laplace transfor...

Magnesium oxide nanotubes of finite length are investigated by the Density Functional Theory (DFT) at the B3LYP/6-31G (d) level. The (6, 0) zigzag and (4, 4) armchair of MgO nanotubes were considered and nuclear magnetic resonance properties including isotropic and anisotropic chemical shielding parameters (CSI and CSA) were calculated for 25Mg and 17O atoms of the optimiz...

background: high density concrete is extensively used for efficient radiation attenuation in radiotherapy rooms and nuclear reactors. over the past eight years, some efficient galena-based concrete samples for shielding x or gamma rays was produced. the goal of this study was to produce a novel high density concrete against neutron and photon radiations using tourmaline and galena. materials an...

We present the basic ideas of the Density Matrix Renormalization Group and report on recent efforts to apply it in large scale nuclear structure calculations.

The properties of symmetric nuclear and pure neutron matter are investigated within an extended self-consistent Green’s function method that includes the effects of three-body forces. We use the ladder approximation for the study of infinite nuclear matter and incorporate the three-body interaction by means of a density-dependent two-body force. This force is obtained via a correlated average o...

dear editor, the big public health concern in this year is the nuclear crisis in japan that causes contamination of nuclides around the world. the effect of the exposure to leaked nuclides from the present nuclear crisis on reproductive health is a topic to be concerned. in my previous publication (1), the evidence on the relationship between nuclear exposure and infertility can be confirmed. h...
