摘　　要：用活化法，在Ｅｎ＝１３．５～１４．７ＭｅＶ中子能区，以５４Ｆｅ（ｎ，ｐ）５４Ｍｎ截面为中子注量标准测量了１０２Ｐｄ（ｎ，ｐ）１０２ｍＲｈ，１０２Ｐｄ（ｎ，ｐ）１０２ｇＲｈ，１０５Ｐｄ（ｎ，ｐ）Ｒｈ，１０６Ｐｄ（ｎ，ｐ）１０６ｍＲｈ的反应截面值；以９３Ｎｂ（ｎ，２ｎ）９２ｍＮｂ截面为中子注量标准测量了１０６Ｐｄ（ｎ，α）１０３Ｒｕ，１０８Ｐｄ（ｎ，α）１０５Ｒｕ；１０２Ｐｄ（ｎ，２ｎ）１０１Ｐｄ和１１０Ｐｄ（ｎ，２ｎ）１０９Ｐｄ的反应截面值．中子能量是用铌锆截面比法测定的．实验的测量误差在６％～２０％范围内．The Cross sections for (n,p),(n,α) and (n,2n) reactions have been measured on palladium isotopes at 13.5～14.7 MeV by the activation technique. The cross sections of the reactions were determined relative to the known cross sections of 54 Fe(n,p) 54 Mn or 93 Nb(n,2n) 92m Nb reactions.Data are reported for the following reactions: 102 Pd(n,p) 102m Rh, 102 Pd(n,p) 102g Rh, 105 Pd(n,p) 105 Rh, 106 Pd(n,p) 106m Rh; 106 Pd(n,α) 103 Ru, 108 Pd(n,α) 105 Ru; 102 Pd(n,2n) 101 Pd and 110 Pd(n,2n) 109 Pd .The neutron energies in the experiment were determined by the cross section ratios for 93 Nb(n,2n) 92m Nb reactions. The errors in our work were from 6% to 20%.Our data were compared with other data published previously.
