Possible Density between Nucleons within Nuclei

Abstract

   The half-life of nucleus can considered as standard of its stability. The half-life correlates , by increasing relation, with the mean binding energy  , which correlates with the ratio       (number of  neutrons to the  number of protons ) .The mean binding energy of  nucleus correlates  also , by increase relation, with mean distances between nucleons and hence with  mean  nucleonic density of this nucleus, whereas the mean distance between  nucleons  smaller than determined  minimum value of mean distance _min  or more than determined maximum value of mean distance _max , and  it has determined  these two values for each value of Z, and also in this work, it were determined the two  values _min   , _max , that opposite them, respectively and that was as attempt to know the productions conditions 0f artificial nuclei.
