Scaling properties of light-cluster production

Z. Chajęcki, M. Youngs, Daniel D. S. Coupland, W. G. Lynch et autres

We show that ratios of light-particle energy spectra display scaling properties that can be accu- rately described by effective local chemical potentials. This demonstrates the equivalence of t/3He and n/p spectral ratios and provides an essential test of theoretical predictions of isotopically …

Angular dependence in proton-proton correlation functions in central 40 Ca + 40 Ca and 48 Ca + 48 Ca reactions

Vladimir Henzl, M. Kilburn, Z. Chajęcki, Daniela Henzlova et autres

The angular dependence of proton-proton correlation functions is studied in central ${}^{\text{40}}\text{Ca}+{\phantom{\rule{0.16em}{0ex}}}^{\text{40}}\text{Ca}$ and ${}^{\text{48}}\text{Ca}+{\phantom{\rule{0.16em}{0ex}}}^{\text{48}}\text{Ca}$ nuclear reactions at $E/A=80$ MeV. Measurements were performed with the High Resolution Array (HiRA) complemented by the 4$\ensuremath{\pi}$ Array at the National Superconducting Cyclotron Laboratory. A striking angular …

Ground-state proton decay of 69Br and implications for the rp-process 68Se waiting-point

Andrew M. Rogers, M.S. Wallace

The first direct measurement of the proton separation energy, Sp, for the proton-unbound nucleus 69Br is reported. Of interest is the exponential dependence of the 2p-capture rate on Sp which can bypass the 68Se waiting-point in the astrophysical rp process. An analysis …

NanoStore: A Concept for Logistical Improvements of Compound Handling in High-Throughput Screening

Neil Benson, Helen Boyd, Jeremy Ramsey Everett, Joachim Fries et autres

Small molecule screening, the systematic encounter of biology space with chemical space, has provoked the emergence of a whole industry that recreates itself by constant iterative improvements to this process. The authors describe an approach to tackle the problem for one of …

Reed-Solomon coding and slow frequency hopping for narrowband digital cellular systems

J. Ketchum, M.S. Wallace

The use of slow frequency hopping in conjunction with Reed-Solomon forward error correcting coding in cellular communication systems is investigated, and the capacity of a configuration which takes a TDMA channel structure as a starting point is discussed. The details of the …

Performance of wideband signaling for slowly fading frequency selective channels

S.J. Howard, M.S. Wallace

The optimum performance of a wideband system operating over slowly fading frequency selective channels is evaluated. Although it is well known that system performance is directly related to the product of RMS delay spread of the channel and operating bandwidth of the …
