Investigation of Shape Coexistence in ¹⁰⁶Cd — •A. Linnemann, C. Fransen, J. Jolie, D. Mücher, and V. Werner — Institut für Kernphysik, Universität zu Köln

Excellent examples of quasi-complete structures representing shape coexistence have been observed during the last decade in the Cd-isotopes e.g. ref[1]. These isotopes form a great test of shape coexistence as here the intruder states have their lowest excitation energy (at mid shell) exactly at the line of stability. This allows the unique possibility to study the six even-even Cd isotopes in an complete way as possible. We have studied recently the lightest stable of those, ¹⁰⁶Cd, using the reactions ¹⁰⁴Pd( α, 2n )¹⁰⁶Cd, ¹⁰⁵Pd( ³He, 2n )¹⁰⁶Cd and the β-decay ¹⁰⁶Cd( p, n )¹⁰⁶In with the HORUS-Spectrometer at the Cologne FN-Tandem accelerator. First results of the analysis will be presented.
