Experimental cross-sections for proton induced reactions on natural molybdenum

Abstract

The experimental cross-sections of the natMo(p,xn)93m+g,94g,95m,95g,96m+gTc, 100Mo(p,x)99Mo and 100Mo(p,2n)99mTc nuclear reactions were measured up to 18.3MeV, by the stacked-foil activation technique at the superconducting linear accelerator of the Institute of Modern Physics, Chinese Academy of Sciences. And the proton beam current was monitored by the independent natCu(p,x)65Zn and natTi(p,x)48V reactions. The experimental results were compared with the literature data taken from EXFOR database, evaluation data of the charged-particle cross section database and theoretical values by using TALYS-1.95 code with six level density models. The obtained results for most of the radionuclides show good agreement with the available literature data. Besides, the theoretical calculations predicted by the TALYS-1.95 code demonstrate similar trends with experimental data. Although in some cases, cross-sections results are sensitive to the nuclear level densities. Evaluated nuclear values of the charged-particle cross section database correspond well with our measurements for 96m+g,99mTcand 99Mo.
