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...

Design and calibration of a passive detector for separating neutron, proton and alpha particles in mixed radiation fields

In this study, calibration process was carried out for deigned new CR-39 nuclear track detector for protons, neutrons and alpha particles separately under the same etching condition. In order to aim this purpose, americium-beryllium standard source (241Am-Be) and Plexiglas phantom for neutron irradiation, brass collimators and americium standard source (241Am) for alpha irradiation and the acce...

NUCLIDES OF ASTROPHYSICS INTEREST WITH MASS NUMBERS CLOSE TO A~80 PNPI participants of the IGISOL/JYFLTRAP collaboration

Nuclei close to the N = Z line in the region near A = 80 play a special role in nuclear astrophysics since the rapid proton (rp) capture process is passing right through them (see Fig. 1). The rp-process, a sequence of rapid proton captures and β-decays, proceeds along the N = Z line up to Ni and it can continue ending in a SnSbTe cycle either in explosive X-ray bursts or in a steady state burn...

  A second-order approximation to the Faddeev-Watson-Lovelace treatment of the rearrangement channel is used in a three-body scattering cross sections. In this formalism, the Three-body wave function is expressed by three coupled integral equations, the Faddeev equations, which contian the two-body (off-shell) transition amplitudes, and proved the uniqueness of their solutions. This amplitude c...
