- We present energy-gain distributions for net one- and two-electron transfer in slow Ar-q+-C-60 collisions. The Delta E-spectra for the former peak at Delta E(1) = 12.9 +/- 0.4 (nl = 7s and 7p), 15.5 +/- 1.0 (n = 10), 15.1 +/- 0.5 (n = 11), and 13.8 +/- 0.

- BACKGROUND: Few studies have focused on risk factors in women's lives concerning psychosocial factors and coronary heart disease (CHD). The present study is one of a series in which a wide range of psychosocial factors will be analysed with a focus on women. Women and men have been compared with respect to sensitivity to psychosocial risk factors regarding CHD. The importance of psychosocial risk factors for women, compared with biomedical risk factors has also been studied. METHODS: A questionnaire (The Stress Profile) was answered by 538 rehabilitation participants (97 women, 441 men) and a reference group (5308 women, 5177 men), aged 40-65 years. Psychosocial factors were investigated using means and b-coefficients. Comparisons between psychosocial and biomedical risk factors were made, with respect to the product of the beta-coefficient and the standard deviation for each compared risk factor. RESULTS: Significant differences appeared concerning five areas: work content, workload and control, physical stress reactions, emotional stress reactions and burnout. All showed that the relative sensitivity was larger for women than for men. Predictive psychosocial risk factors for women with respect to CHD were physical stress reactions, emotional stress reactions, burnout, family relationships and daily hassles/satisfactions, and they were on approximately the same level as biomedical risk factors. CONCLUSIONS: Women appear to be more sensitive than men with respect to psychosocial risk factors for CHD, and the predictive ability of psychosocial risk factors shows great importance. Actions against unhealthy psychosocial conditions are recommended. Both presumptive CHD patients and others might benefit from preventive actions, and since women are more sensitive they will probably gain more than men.

- We have extended the recently developed dynamical classical over--barrier model for charge transfer in soft ion--cluster collisions in order to simulate the projectile kinetic energy gain of 3.3q keV Arq+ ions in large impact parameter collisions with neutral C60 targets. Our semi-classical theory allows for the direct calculation of the energy defect Q and of the projectile kinetic energy gain in two different ways, either as difference of electronic binding energies before and after the collision or by integration of the dynamically varying force between the collision partners along the trajectory. A comparison between the two ways provides an intrinsic test of the model calculations. Comparison with recent experimental data shows good agreement in the main features of the projectile energy gain spectra and facilitates their interpretation in terms of the number of transferred electrons and projectile shells into which electrons are captured.
