Applicability of the Hauser-Feshbach approach for the determination of astrophysical reaction rates
(1997-08-04)
Nuclear Astrophysics requires the knowledge of reaction rates over a wide range of nuclei and temperatures. In recent calculations the nuclear level density – as an important ingredient to the statistical model (Hauser-Feshbach) ...
Uncertainties in direct neutron capture calculations due to nuclear structure models
(1997-08-04)
The prediction of cross sections for nuclei far off stability is crucial in the field of nuclear astrophysics. For spherical nuclei close to the dripline the statistical model (Hauser-Feshbach) approach is not applicable ...
The r-process in the high entropy bubble
(1997-08-04)
The endpoint of the rp-process
(1997-08-04)
An approximation for the rp-process
(1997-07-20)
Hot (explosive) hydrogen burning, or the rapid proton capture process (rp-process), occurs in a number of astrophysical environments. Novae and X-ray bursts are the most prominent ones, but accretion disks around black ...
Sm-144-alpha optical potential at astrophysically relevant energies derived from Sm-144(alpha,alpha) Sm-144 elastic scattering
(1997-03)
For the determination of the Sm-144-alpha optical potential we measured the angular distribution bf Sm-144(alpha, alpha)Sm-144 scattering at the energy E(lab)=20 MeV with high accuracy. Using the known systematics pf ...
Neutron capture reaction rates of unstable isotopes in the s-process branchings
(SOC ITALIANA FISICA, 1997)
Neutron-rich isotopes Ti-54-57
(1996-12)
The neutron-rich isotopes Ti-54-57 and Cr-58-60 are produced by fragmentation of a 64.5 MeV/nucleon Cu-65(26+) beam in a 90 mg/cm(2) Be-9 target. Following particle identification by energy loss and time of flight, the ...
Neutron-induced nucleosynthesis
(1996-11)
Neutron-induced nucleosynthesis plays an important role in astrophysical scenarios like in primordial nucleosynthesis in the early universe, in the s-process occurring in Red Giants, and in the cu-rich freeze-out and ...
Ge-70(alpha,gamma)Se-74 cross section measurements at energies of astrophysical interest
(1996-07)
The cross section of the reaction Ge-70(alpha, gamma)Se-74 has been measured over the bombarding energy range of 5.05 MeV <E(alpha) <7.80 MeV using single and coincidence gamma spectroscopy techniques. The experimental ...
