چکیده

The ratio of symmetry energy coefficient relative to the temperature, asym/T , has been extracted as a function of Z from the variance of the observed isotope distributions from the experiments described in Ref.[1]. In order to explore the relation between the symmetry energy term in the free energy and the variance of the isotope distribution, Ono et al. introduced a generalized function K(N,Z) for the free energy in Ref. [2] as given below.

Modeling the distribution of deposited energy by alpha particles from Radon 223 decay and its effect on DNA

 The ionizing radiations, through physical and chemical processes, lead to simple and complex single- and double- strand breaks, as well as base lesions to the DNA. In this study, taking into account all the physical and chemical processes involved in the interaction of ionizing radiation with matter, the initial damage induced to DNA was evaluated for 5.7 MeV alpha-rays from Radon 223 isotope....

The relationships between carbon isotope discrimination and photosynthesis and rice yield under shading

The measurement of carbon isotope discrimination (∆) provides an integrated insight into theresponse of plants to environmental change. To investigate the potential use of ∆ for identifyingshade tolerance in rice, five rice varieties were selected and artificially shaded (53% lightreduction) during the grain-filling period in 2010 and 2011, in Sichuan, China. Shadingtreatment had a significant ...

Calculation of the rotational bands for the 20Ne isotope

The phenomenon of clustering in light nuclei is one of the interesting topics while its study is difficult. In this article, a simple model (the two-particle model which includes a core and a cluster) is presented for the investigation of the positive and the negative parity of rotational bands of 20Ne isotope. The Deng-Fan and the Hellman potentials are considered as the core and the cluster p...
