Proton capture cross-section of 106,108Cd for the astrophysical p-process

Study of Radiative Capture Reactions in the Astrophysical P-process

The cross sections of 70 Ge(;) 74 Se and 144 Sm(;) 148 Gd reactions have been measured over the bombarding energy ranges of 5.05 MeV<E <7.80 MeV and 10.5 MeV<E <13.4 MeV, respectively. The results are compared to statistical model calculations. The importance of further reaction studies is emphasized.

Proton induced reactions and the astrophysical p process Ph.D. thesis

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...

Alpha induced reaction cross section measurements on 162Er for the astrophysical γ process

a r t i c l e i n f o a b s t r a c t The cross sections of the 162 Er(α, γ) 166 Yb and 162 Er(α, n) 165 Yb reactions have been measured for the first time. The radiative alpha capture reaction cross section was measured from E c.m. = 16.09 MeV down to E c.m. = 11.21 MeV, close to the astrophysically relevant region (which lies between 7.8 and 11.48 MeV at 3 GK stellar temperature). The 162 Er(...

The proton capture cross sections of the two most proton rich, stable isotopes of Cadmium have been measured for the first time in the energy range relevant to the astrophysical p–process between Ep=2.4 and 4.7MeV. The Cd(p,γ)In and Cd(p,γ)In cross sections have been determined using the activation technique. Highly enriched as well as natural Cd targets have been irradiated with proton beams f...
