    Notes: Abstract In a long-term follow-up study, 524 (93%) of 563 consecutive medical and psychiatric patients, who received an average of 8 sesisons of biofeedback and relaxation training, provided follow-up evaluations of treatment outcome. Seventy-five percent reported maximum, significant, or moderate improvement. There was a significant positive association between the percent of patients improved and the number of treatment sessions up to 10 sessions, but not thereafter. Symptom frequency decreased by 54% and symptom severity by 30%. About 54% of the medicated patients reported a decrease in medication. No differential therapist effects were found. About twice as many patients rated relaxation training as most helpful compared with the audio/visual signals from biofeedback instruments.

    Notes: Abstract Double differential cross sections for the emission of Delta-electrons have been measured in fast uranium-rare gas collisions. The well-known Binary Encounter peak reveals unexpected structures for certain observation angles and its intensity increases towards smaller angles, which is in contradiction to results and scaling laws obtained by experiments with light ion impact. The observed dependencies are fairly well described by recent calculations in the framework of IA and CTMC. From systematic experimental as well as theoretical studies we can derive that the potential of the partially stripped projectile ion gives rise to rainbow and glory scattering of the target electron in the field of the projectile. The rainbow scattering is observed in the laboratory frame as pronounced interference structures, whereas the glory scattering is responsible for the steep increase of the cross sections for binary-encounter electrons towards small laboratory ejection angles. The observed effects have a dramatic influence on the commonq 2 scaling laws derived from experiments with light ions. Furthermore, since the binary-encounter electrons ejected at forward angles have approximately twice the projectile velocity, these new phenomena have an important influence on the electronic stopping power of heavy ions and therefore have to be taken into account for the investigation of radiation damage by these ions e.g. in biological matter.
