A good description of the excited positive and negative parity states of radium nuclei (Z =88, N =130-142) is achieved using the interacting boson approximation model (IBA-1). The potential energy surfaces, energy levels, parity shift, electromagnetic transition rates B(E1), B(E2) and electric monopole strength X(E0/E2) are calculated for each nucleus. The analysis of the eigenvalues of the model Hamiltonian reveals the presence of an interaction between the positive and negative p...

On the elliptic function arising from the theta functions and Dedekind's [eta]-function.
Journal of Mathematics and Statistics ; Abstract: It's a reality that there is a relationship between the sigma function of Weierstrass and theta functions. An elliptic function can be set up using the theta functions just as it can be astablished with the help of sigma function of Weierstrass and two relations between the Dedekind's
