Search for three-nucleon force effects in analyzing powers for p-->d elastic scattering.

A series of measurements have been performed at KVI to obtain the vector analyzing power A(y) of the (2)H(p-->,pd) reaction as a function of incident beam energy at energies of 120, 135, 150, and 170 MeV. For all these measurements, a range of theta(c.m.) from 30 degrees to 170 degrees has been covered. The purpose of these investigations is to observe possible spin-dependent effects beyond two-nucleon forces. When compared to the predictions of Faddeev calculations, based on two-nucleon forces only, significant deviations are observed at all energies and at center-of-mass angles between 70 degrees and 130 degrees. The addition of present-day three-nucleon forces does not improve the description of the data, demonstrating the still insufficient understanding of the properties of three-nucleon systems.

In a total of 10,000 thoracosurgical operations the percentage of patients being older than 70 years amounted to 1.1. Most of these patients underwent surgery for bronchial carcinoma. The postoperative mortality rate in these patients could be lowered to 1.0% (1977/78). 25% of the patients older than 70 years who suffered from lung cancer stage I and II survived for more than 5 years after operation.

[Analysis and trends of treatment in cancer of the lung (author's transl)]. / Analyse und Entwicklungstendenzen in der Chirurgie des Bronchialkarzinoms.

From 1953 to 1978 3439 patients suffering from bronchial carcinoma underwent operation. Due to the changing conditions of mass X-ray early detection of lung cancer decreased. This was followed by a declining number of operations but also by an increase in pneumonectomies (1974 to 1978). The average number of exploratory thoracotomies amounts now to 14% with increasing tendency, especially in patients younger than 50 years of age. Above 70 years lung resections are only possible in rare cases. The postoperative mortality rate (till 4 weeks after surgery) is now at 1,0%. After resection or pneumonectomy more than 40% of the patients will survive for 5 years. The authors recommend lung resection--if technically possible--also in a progredient state of the tumour.
