Talmi spent sabbatical years at Princeton, Stanford, Massachusetts Institute of Technology (MIT), Yale and other universities as a visiting professor.

[4] In addition to his influential papers and conference talks, Talmi also wrote two books that served as guides and companions to generations of nuclear structure theorists.

[5] The atomic nucleus can be composed of a large number of protons and neutrons which move due to strong interactions between them.

This picture of the nucleus is called the nuclear shell model[6] to obtain the information from experimental data and use it to calculate and predict energies which have not been measured.

Talmi developed a method[7] to obtain the information from experimental data and use it to calculate and predict energies which have not been measured.

[8] Talmi also participated in the study of explicit fermion–boson mappings required to connect the interacting-boson model with its shell-model roots and in the introduction of the boson F-spin analog to nucleon isospin.
