The cross section data of ¹²C(n,2n)¹¹C and ²⁰⁹Bi(n,xn)(x=3,12) reactions and the cross section data which produce ⁵⁶Mn, ⁵⁴Mn, ⁵²Mn, ⁵⁸Co, ⁵⁷Co, ⁵⁶Co, ⁵⁵Co, ⁵⁹Fe from ⁵⁹Co reactions and ⁵⁶Mn, ⁵⁹Fe, ⁶⁰Co, ⁵⁸Co, ⁵⁷Co, ⁵⁶Co, ⁶⁴Cu, ⁶¹Cu, ⁶⁰Cu from ^natCu reactions have been measured in the quasi-monoenergetic p-⁷Li neutron fields in the 20- and 150-MeV energy range. The irradiation experiments were performed at four cyclotron facilities:(a) the Institute for Nuclear Study (INS), University of Tokyo;(b)the Cyclotron and Radioisotope Center, Tohoku University; (c) the Takasaki Research Establishment (TIARA), Japan Atomic Energy Research Institute; and (d) the Institute of Physical and Chemical Research (RIKEN). The neutron spectrum has been measured with the time-of-flight method using an organic liquid scintillator, and the absolute value of peak neutron fluence has been estimated from the activation method of lithium target at INS, RIKEN, and the proton recoil counter telescope at TIARA.
