Measurements of angular distribution of atoms sputtered from copper
gold element samples and Cu
0.7
Au
0.3
alloy samples by 27 keV argon ions irradiation are reported. The following results are noteworthy: (1) All angular distributions were over cosine. The exponent
n
in fitting functions of the from con
n
θ
was obtained
n=1.56 and 1.61 for copper and gold samples
and n=1.78 for Cu
0.7
Au
0.3
alloy samples respectively; (2) The angular distributions of the component atoms sputtered from Cu
0.7
Au
0.3
alloy showed that the copper ejected was preferential.
