Alpha decay of neutron resonances in the $sup 149$Sm(n,$alpha$$)$$sup 146$Nd reaction (in Russian)
Technical Report
·
OSTI ID:4936379
The values of the total and partial alpha widths of the neutron resonances of the /sup 150/Sm nucleus, obtained from the /sup 149/Sm(n, alpha )/ sup 146/ Nd reaction in the neutron energy range of 0.025 to 40 eV, are presented. The experimental results are compared with the predictions of the statistical alpha -decay model of highly excited states. The form of the E/sub 0/ = 0.87 eV resonance is described, taking into account the Doppler effect, as well as the interference between the resonances of 0.87 and 0.098 eV.
