Ground-state proton decay of 69Br and implications for the 68Se astrophysical rapid proton-capture process waiting point.
We report on the first direct measurement of the proton separation energy for the proton-unbound nucleus (69)Br. Bypassing the (68)Se waiting point in the rp process is directly related to the 2p-capture rate through (69)Br, which depends exponentially on the proton separation energy. We find a proton separation energy for (69)Br of Sp((69)Br )= -785(-40)(+34) keV; this is less bound compared t...
متن کاملRecent Developments on Kaon Condensation and Its Astrophysical Implications
We discuss three different ways to arrive at kaon condensation at nc ≃ 3n0 where n0 is nuclear matter density: (1) Fluctuating around the n = 0 vacuum in chiral perturbation theory, (2) fluctuating around nVM near the chiral restoration density nχ where the vector manifestation of hidden local symmetry is reached and (3) fluctuating around the Fermi liquid fixed point at ∼ n0. They all share on...
متن کاملProton radiobiology and its clinical implications
Denser ionisation clustering and complex DNA damage in proton Bragg peaks far exceeds that seen with conventional X-rays. This results in more efficient cell sterilisation, quantified by the relative biological effectiveness (RBE). Currently, a 1.1 RBE is used to determine the clinical proton doses by dividing the usual X-rays dose by this amount. This number, derived from short-term experiment...
متن کاملSome Astrophysical Implications
We have calculated the rate coefficients for D(1s) + H ⇆ D +H(1s) using recently published theoretical cross sections. We present results for temperatures T from 1 K to 2×10 K and provide fits to our data for use in plasma modeling. Our calculations are in good agreement with previously published rate coefficients for 25 ≤ T ≤ 300 K, which covers most of the limited range for which those result...
متن کاملAstrophysical Implications Of
The discovery of the gravitational-wave (GW) source GW150914 with the Advanced LIGO detectors provides the first observational evidence for the existence of binary black hole (BH) systems that inspiral and merge within the age of the universe. Such BH mergers have been predicted in two main types of formation models, involving isolated binaries in galactic fields or dynamical interactions in yo...
