On the average gamma-transition strength of a compound nucleus and an application to 74Se

Extraction of level density and γ strength function from primary γ spectra

“…A recent compilation on average γ transition strengths for M1, E1 and E2 transitions is given in Ref. [7]. The uncertainties concern the absolute strength as well as how the strength depends on the γ transition energy.…”

“…[20]), some transitions deviate many orders of magnitude from this approximation. A compilation of average γ transition strengths for dipole and electric quadrupole transitions can be found in [21]. The uncertainty of the γ strength function concerns the absolute value and the γ energy dependence.…”

Folding-type coupling potentials in the context of the generalized rotation–vibration model

“…MeV, theoretical calculations (from [31]) indicate that the major contributions of the decay of the compound nucleus correspond to the one neutron, one proton and two neutrons evaporation, and that the total fusion cross section is about 40% larger than the cross section of the one neutron evaporation mode. For this system, there are two different data sets for one neutron evaporation [28] and [29], and we have included in figure 10 these cross sections multiplied by 1.4 (in order to compare with the theoretical fusion cross section).…”
