摘      要：The neutron response function and detection efficiency of a spherical proton recoil proportional counter (SP) play key roles in precise measurement of neutron spectra of the interior *** this paper,the response functions and detection efficiency of three SPs developed at CAEP are simulated by *** simulated spectra are compared with pulse-height spectra measured at 0.165,0.575,1.4,and 14.1 MeV of incident *** the calculated detector efficiencies agree within 5%with the data obtained by neutron activation.
