β¦ Synopsis
In the framework of the quasiparticle-phonon model, we study the non-statistical proton decay of excited states in odd nuclei towards low-lying collective states. Partial cross sections and branching ratios for the proton decay of the high angular momentum states in 41 Sc, 59 Cu and 91 Nb are evaluated. The calculated branching ratios predict strong direct proton decays to the low-lying vibrational states in 41 Sc and 91 Nb. A general agreement with existing experimental data is found.

Mirror Ξ²-transitions should have similar strengths as long as binding energy, Coulomb energy and other explicitly breaking effects are small. However, large Ξ²-decay asymmetries have been observed in the decay of 9 C [1] and the decay of its mirror nucleus 9 Li [2]. These asymmetries could be the ind
The decay properties of low-lying collective states in 132 Ba were studied by means of Ξ³ spectroscopy following the Ξ²-decay of the 2 -ground state (T 1/2 = 4.8 h) and a 6 -isomer (T 1/2 = 24.3 min) of 132 La. The lanthanum nuclei were produced at the Cologne FN TANDEM accelerator using the reaction
