- The MEGA experiment, which is a search for the decay murarregamma with a branching ratio sensitivity of about 10-13, employs highly modular, fast detectors, state-of-the-art electronics, and a staged trigger with on-line filters. The detectors are contained in a 1.5-T solenoidal field produced by a superconducting magnet. Positrons are confined to the central region and are measured by a set of thin MWPCs. Photons are measured by one of four layers of pair spectrometers in the outer region. Most aspects of the design have been validated in engineering runs; data taking will begin in 1990 with much of the electron arm and one pair spectrometer layer installed.

- A total of 1280 80-year-old men in the community of Malmö were questioned about smoking habits and the occurrence of cardiovascular disease (CVD). After a careful medical and duplex ultrasound examination, four groups were selected for further studies: (1) no CVD, non-smokers: (2) no CVD, smokers: (3) CVD, smokers: (4) CVD, non-smokers. In total 122 individuals participated. The average tobacco consumption by smokers was 13 g d-1 for 59 years. In the CVD group 45% of subjects had atherosclerotic symptoms at more than one site. Smoking was found to be correlated with lower extremity atherosclerosis, cholesterol and LDL cholesterol were correlated with carotid artery lesions and pathological ankle/arm index, and blood pressure was correlated with lower extremity lesions. In contrast with middle-aged populations, individuals with an increasing degree of lesions in the lower extremities had a larger percentage of high glutathione transferase activity than subjects without CVD. Smokers had significantly lower pyridoxal-5-phosphate levels than non-smokers. It is concluded that some heavy smokers might reach an advanced age in good health. Smoking was also operative as a risk indicator for lower extremity atherosclerosis in 80-year-old individuals.

Super-Allowed Beta-Decay of Nuclei at the Drip-Line

- 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.
