Average Nuclear properties based on statistical model
Description
The rough properties of nuclei were investigated by statistical model, in systems with the same and different number of protons and neutrons, separately, considering the Coulomb energy in the last system. Some average nuclear properties were calculated based on the energy density of nuclear matter, from Weizsscker-Beth mass semiempiric formulae, generalized for compressible nuclei. In the study of as surface energy coefficient, the great influence exercised by Coulomb energy and nuclear compressibility was verified. For a good adjust of beta stability lines and mass excess, the surface symmetry energy were established. (M.C.K.)

Propriedades grossa dos nucleos foram investigadas atraves do modelo estatistico, em sistemas com numero de protons e neutrons iguais e diferentes, separadamente, sendo que somente neste ultimo foi considerada a energia Coulombiana. Conhecendo-se a densidade de energia de materia nuclear, a partir da formula semi empirica de massa de Weizsscker-Bethe, generalizada para nucleos compressiveis, foram calculadas certas propriedades nucleares medias. No estudo do coeficiente as da energia de superficie verificou-se a grande influencia exercida pela energia Coulombiana e pela compressibilidade de nuclear. Para um bom ajuste de linhas de estabilidade beta e do excesso de massa, foi constatada a importancia da energia de simetria de superficie. (Autor)Files
