โœฆ Synopsis

The fl-delayed s-particle decay of a6K has been measured in order to search for natural parity states near the proton threshold in Z~Ar. Such states could correspond to resonances in the reaction 35C1(p,(~)32S and might influence mass flows in explosive hydrogen burning scenarios appreciably. We have found evidence for a new s-particle emitting state, corresponding to a resonance energy of E~b=351 keV. Possible implications for the nucleosynthesis during neon nova outbursts are discussed.

Properties of the proton drip line nuclei 6~As, 69Br and 73Rb are important for the prediction of the nucleosynthesis in very high-temperature hydrogen-burning scenarios, such as x-ray bursts. We describe an experimental program at TRIUMF which is designed to measure the quantities of astrophysical interest.

The differences between burning of explosives and detonation are reviewed in the light of a number of research reports, and factors affecting the transition are noted. The acceleration of burning of granular explosives is discussed, with notes on effect of particle size and charge density, followed
