Large scale shell model calculations for the yrast line of 138Xe

We have adopted an importance sampling iterative matrix diagonalization algorithm to compute a large scale shell model calculation of the yrast spectrum of 138 Xe up to high spin thereby extending a previous calculation confined to low-lying angular momenta. An effective nucleon–nucleon interaction derived from the CD-Bonn nucleon-nucleon potential is used to compute energies, E 2 transition probabilities, and occupation numbers. A satisfactory agreement with the experimental data is reached.
