Restricted spin-range correction in the Oslo method: The example of nuclear level density and γ -ray strength function from Pu239(d,pγ)

Abstract: The Oslo Method has been applied to particle-γ coincidences following the 239 Pu(d,p) reaction to obtain the nuclear level density (NLD) and γ-ray strength function (γSF) of 240 Pu. The experiment was conducted with a 12 MeV deuteron beam at the Oslo Cyclotron Laboratory. The low spin transfer of this reaction leads to a spin-parity mismatch between populated and intrinsic levels. This is a challenge for the Oslo Method as it can have a significant impact on the extracted NLD and γSF. We have developed an iter… Show more

“…These values are very close to literature [40,44,45]. In addition, we obtained a normalization factor for the γSF of 2.8 AE 0.3, which, combined with the model of [41], gives a γSF for 240 Pu that compares well with the experimental results of [46]. The good agreement of these model ingredients with previous work demonstrates the validity of our adjustment procedure.…”

“…This again influences the primary γ -ray spectra P(E x , E γ ). A slope correction of the γ SF might therefore be necessary in particular for sub-Coulomb barrier reactions [12][13][14][15][16][17]58]. To verify whether such a correction is necessary, the J π distribution populated by the (d, pγ ) reaction has been investigated with the statistical nuclear reaction code TALYS (v1.95) [59] for the deuteron absorption compound reaction formation assuming isotropic emission.…”

“…Since then, many heavy deformed even-even and odd-mass rare-earth nuclei have been systematically investigated. So far, the SR mode has been experimentally observed in vibrational and rotational [8], as well as in γ -soft nuclei [9,10] and has also been observed in the actinide region [11][12][13][14][15][16][17], as well as in the rare-earth mass region [4,[18][19][20][21][22][23][24][25][26][27].…”
