**Analysis**
The text appears to be discussing the development of South Africa's uranium enrichment program, including the country's efforts to collaborate with other countries, particularly West Germany, in this endeavor. The text highlights the informal relationships established between South African scientists and their West German counterparts, as well as the eventual breakdown of these relationships due to disagreements over financial arrangements and risk sharing. The text suggests that the informal ties contributed to the advancement of South Africa's enrichment program, but the extent of this contribution is unclear.
