Abstract
First predictions for specific case of the particle-hole-core coupling model which takes advantage of symmetries of a triaxial rotor with gamma = 90 degrees are reviewed. Results of the model calculations point towards existence of stable chiral geometry in specific configurations involving high-j orbitals. Next, experimental information on doublet bands built on unique parity, pi(h)11/2(Vh)11/2 intruder states in odd-odd Pr-134 is discussed; in particular observed disagreements between electromagnetic transitions within the doublet structures which is pointed out as inconsistent with the simplest models. Finally, the unique experimental infrastructure developed at the Tri-University Meson Facility (FRIUMF) Canada's National Laboratory for... (More)

Finally, the unique experimental infrastructure developed at the Tri-University Meson Facility (FRIUMF) Canada's National Laboratory for Particle and Nuclear Physics is presented including a range of isotopes in the mass 130 region that are accessible as beams and which can possibly yield significant new information in investigations of nuclear chirality.
