CXIX. Spallation of vanadium, manganese, and cobalt with187 m e v protons

Summary This paper describes measurements of the yield of various spallation products from vanadium, manganese, and cobalt. From the experiments it is concluded that in the spallation of medium weight elements with high energy protons, the total cross section per mass number decreases almost exponentially with increase in the difference between the actual mass number and the mass number of the target nucleus. It is also concluded that for a given mass number the cross sections of the isobars are approximately represented by a Gaussian distribution.
