Investigation of giant-dipole-resonance decay in the (γ, n) reactions on 52Cr and 51V nuclei
The cross sections for the emission of fast neutrons ( ɛ n > 3.7 MeV) in the reactions 52 Cr( γ, n ) 51 Cr and 51 V( γ, n ) 50 V at incident-photon energies in the range between 16.0 and 25.8 MeV were studied. The neutron energy spectra were measured at the bremsstrahlung-photon endpoint energies...

| Zusammenfassung: | The cross sections for the emission of fast neutrons (
ɛ
n
> 3.7 MeV) in the reactions
52
Cr(
γ, n
)
51
Cr and
51
V(
γ, n
)
50
V at incident-photon energies in the range between 16.0 and 25.8 MeV were studied. The neutron energy spectra were measured at the bremsstrahlung-photon endpoint energies of 18.5, 21.0, and 23.0 MeV for the
52
Cr and
51
V nuclei and at the bremsstrahlung-photon energy of 25.5 MeV for the
51
V nucleus. Special features of giant-dipole-resonance decay that are associated with the existence of a structure in photoneutron cross sections and spectra are discussed. |
