>A Dalitz plot of l.6xl0/sup 6/K/sub L//sup 0/ yields pi mu nu decays has been stu died to measure the t dependence of the vector and scalar form factors. The observed slopes, lambda /sub +/ =0.030 plus or minus 0.003 and lambda /sub 0/=0.020 plus or minus 0.003, are com patible with current- algebra and soft-pion predictions, mu -e universality, and K*(890) dominance of the vector form factor.
