| Abstract: | The mean cross sections of the 102Pd(n,p)102,102mRh and 103Rh(n,2n)102,102m Rh reactions were experimentally determined by irradiating palladium and rhodium samples for 1 week at an equivalent fission flux of 3 × 1013 n. cm−2 . s−1. The equivalent fission neutron flux was determined using six reference threshold reactions [47Ti(n,p)47Sc; 58Ni(n,p)58,58mCo; 54Fe(n,p)54Mn; 46Ti(n,p) 46Sc; 92Mo(n,p) 92mNb and 55Mn(n,2n) 54Mn] and appeared to be unperturbed.Thorough radiochemical decontaminations were required in order to separate the 102,102mRh activities from the high thermal neutron induced palladium, silver and/or iridium activities.The results are compared with the values predicted by empirical relationships. |
