Abstract: The Bethe-Weizsäcker mass formula has been proposed with its different parameters representing different aspects of energy involved in the binding energy of the nucleus (shell corrections are not considered in this work) [1], [2]: B(A,Z)=a_v A-a_s A^(1/3)-a_c Z(Z-1) A^(-1/3)-a_a (N-Z)^2/A±a_p A^(-3/4) We have used the least-squares adjustments and the new evaluated binding energy table, containing more than 3400 nuclei (updated 2016) [5] to determine empirically the parameters of the formula. Keywords : Parameters of mass formula, least-squares adjustments, mass data table.
