Many isotopes of Np,Pu,Am,and Cm around the N=126 shell still have not been produced in the *** study aims to investigate the cross sections and yields of the neutron-deficient nuclei of Np,Pu,Am,and Cm produced in the proton-induced spallations of transuranium *** isospin-dependent quantum molecular dynamics(IQMD)model is applied to study the dynamical process of reaction,and the subsequent decay process is simulated by the GEMINI++*** IQMD-GEMINI++model is applied to calculate the cross section,kinetic energy,and angular distribution of the isotopic productions around N=*** Lindhand,Scharff,and Schiott theory is applied to calculate the energy loss of different heavy nuclei in the target material.A comparison between the data and the calculations shows that the IQMD-GEMINI++model can reproduce the production cross sections of the neutron-deficient nuclei in spallation within approximately 1.5 orders of *** maximum cross section of the undiscovered isotopes of Np,Pu,Am,and Cm is about 10-5 mb,while the kinetic energies of the productions are all less than 16 *** angular distribution shows that the emission direction of production is mostly at a backward *** range of production in the target is within the range of 10-7to *** range is the effective target thickness for the online identification of undiscovered *** on the effective thickness of the target and assuming an intensity of 120μA for the proton beam,the yields of the undiscovered neutron-deficient nuclei are *** of the undiscovered isotopes of Np,Pu,Am,and Cm by the proton-induced spallations of transuranium elements are ***,experimental techniques for online identification of neutron-deficient nuclei produced in proton-induced spallation should be developed.
