“…As it was pointed out in the introduction the experimental results do not show a unique picture. In the energy region beyond 35 MeV there is an overall agreement of the data of [4,6,8,9,11,12,42], whereas in the dipole resonance region big discrepancies are present.…”

Two-body photodisintegration ofHe4with full final state interaction

et al. 2004

View full text Add to dashboard Cite

The cross sections of the processes 4 He(γ, p) 3 H and 4 He(γ, n) 3 He are calculated taking into account the full final state interaction via the Lorentz integral transform (LIT) method. This is the first consistent microscopic calculation beyond the three-body breakup threshold. The results are obtained with a semirealistic central NN potential including also the Coulomb force. The cross sections show a pronounced dipole peak at 27 MeV which lies within the rather broad experimental band. At higher energies, where experimental uncertainties are considerably smaller, one finds a good agreement between theory and experiment. The calculated sum of three-and four-body photodisintegration cross sections is also listed and is in fair agreement with the data.

Photodisintegration Cross Section of the ReactionHe4(γ,p)H3between 22 and 30 MeV

et al. 2012

View full text Add to dashboard Cite

The two-body photodisintegration cross section of (4)He into a proton and triton was measured with monoenergetic photon beams in 0.5 MeV energy steps between 22 and 30 MeV. High-pressure (4)He-Xe gas scintillators of various (4)He/Xe ratios served as targets and detectors. Pure Xe gas scintillators were used for background studies. A NaI detector together with a plastic scintillator paddle was employed for determining the incident photon flux. Our comprehensive data set follows the trend of the theoretical calculations of the Trento group very well, although our data are consistently lower in magnitude by about 5%. However, they differ significantly from the majority of the previous data, especially from the recent data of Shima et al. The latter data had put into question the validity of theoretical approaches used to calculate core-collapse supernova explosions and big-bang nucleosynthesis abundances of certain light nuclei.

A continuum shell model has been constructed which allows inclusion of any nonspurious states of the core nuclei and any nonspurious states of the composite system. The resulting coupled-channels solutions are antisymmetric and translationally invariant. These wave functions can be used to calculate many nuclear phenomena, from capture reactions at astrophysical energies, to knockout reactions at low energies, to nucleon scattering and charge exchange at intermediate energies. The model is used to investigate the
