1 Prior to the usage of lighter materials in car manufacturing, a typical Volvo could be assumed to contain 1100 kg of iron. Such a car is bombarded by a flux of 1011 ve neutrinos from the sun per cm and per second, 24 hours per day. These neutrinos may interact with one of the nucleons in 56 Fe converting it to the radioactive isotope 56 Co in its ground state. a) Give the complete reaction for the converting process to 56 Co. b) Explain the possible spin and parity of the 56 Co ground state. c) 56 Co can decay in two different ways. Give both reaction equations. For which kind of decay is the Q value larger and why? d) 56 Fe in the Volvo has been exposed to neutrinos since Fe was formed, and the activity from 56 Co has reached an equilibrium value. The neutrino induced reaction has a cross section of 10-20 b. How large is the activity of the Volvo from 56 Co decays induced by solar neutrinos?
