EXCITATION CURVES FOR SOME REACTIONS OF Al、Ti、V AND I

  • Excitation curves for the reaction 27Al(n,α24Na,46Ti(n,p46Sc,48Ti(n,p48Sc,51V(n,α48Sc and 127I(n,2n126I have been measured by the activation method in the4.5—18.3 MeV energy region.The cross section for the reactio 27Al(n,α24Na was determined at 14.61±0.20 MeV.The measurement of neutron flux was performed using the associated particle method.The cross sections for other reactions were de-termined relative to the measured 27Al(n,α24Na cross section.The resulting activities were measured employing a calibrated NaI(TI)scintillation counter.The values obtained were 117.5±3.0 mb,291.4±14.0mb,63.7±3.2 mb,16.8±0.9mb and 1656±68 mb respectively.A brief comparison with existing data was made.

EXCITATION CURVES FOR SOME REACTIONS OF Al、Ti、V AND I

Abstract: Excitation curves for the reaction 27Al(n,α24Na,46Ti(n,p46Sc,48Ti(n,p48Sc,51V(n,α48Sc and 127I(n,2n126I have been measured by the activation method in the4.5—18.3 MeV energy region.The cross section for the reactio 27Al(n,α24Na was determined at 14.61±0.20 MeV.The measurement of neutron flux was performed using the associated particle method.The cross sections for other reactions were de-termined relative to the measured 27Al(n,α24Na cross section.The resulting activities were measured employing a calibrated NaI(TI)scintillation counter.The values obtained were 117.5±3.0 mb,291.4±14.0mb,63.7±3.2 mb,16.8±0.9mb and 1656±68 mb respectively.A brief comparison with existing data was made.
