TITLE=/ Angular-momentum effect in the fusion reaction of 141Pr with
40Ar projectiles /;
PURPOSE=/ To attempt direct measurements of the cross sections for
both particle evaporation and fission in the reaction of
141Pr with 40Ar ions by a radiochemical method to elucidate
the relation of the critical angular momenta with the
measured cross sections /;

target stack was calculated using the OSCAR code [K. Hata and H.
