TITLE=/ Reactions on 209Bi induced by intermediate energy protons
and the effect of direct reactions /;
PURPOSE=/ To measure the cross sections and the nuclear recoil
renges for the (p,3n), (p,4n) and (p,p3n) reactions, and to
study whether the direct process occurs in reactions on such
a heavy nucleus as 209Bi /;

/* Experimental Method:
- Activation (Bombarded for 1.5 hours with 52 MeV protons)
- Stacked target irradiation (Pair of target foils and catcher
foils were formed into a stacked-foil target.)
- Energy degradation by foils (Using the energy loss and range
graphs of Marion et al. [J.B.Marion et al., Nuclear reaction
analysis (North-Holland, Amsterdam, 1968)])
