- In the first experiment at the newly constructed ISOLDE Facility the first-forbidden beta-decay of Ne-17 into the first excited state of F-17 has been measured. It is a factor two faster than the corresponding mirror decay and thus gives one of the largest recorded asymmetries for beta decays feeding bound final states. Shell-model calculations can only reproduce the asymmetry if the halo structure of the F-17 state is taken into account.

- We have investigated the continuous particle spectra following the beta decay of the neutron-rich nuclei that terminate the mass 6, 8, 9 and 11 isobaric chains. Strong beta transitions feeding the very top of the spectrum are found systematically. The favoured states are within a few MeV of the energy of the initial state. This phenomenon seems to be linked to the occurrence of a di-neutron structure or neutron halo in the drip-line nuclei.

- We evaluated the prognosis for 419 patients admitted to hospital due to suspected acute myocardial infarction (AMI) who developed ST-T changes, but no rise in serum enzyme activity, and compared it to that of 508 patients developing non-Q-wave AMIs. We conclude that these patients have a high 1-year mortality (13%), although significantly lower than in patients with non-Q-wave AMIs (31%). The mortality is higher in patients with only ST depression (n = 86; 22%) than in patients with only T-wave inversion (n = 264; 8%).
