THEORETICAL-STUDIES OF THE 3-BODY RECOMBINATION OF THE MUONIC HELIUM ION (HE-MU-)(+) IN GASEOUS HELIUM

The classical trajectory method is employed to calculate the rate coef ficient k(r) for the reaction (He-mu-)(+)+He+He-->(Hemu-He)(+)+He at t emperatures in the range 200 less than or equal to T less than or equa l to 350 K. The obtained rates can be well fitted by the function k(r) =AT(alpha) exp(B/T) with A=4.3756x10(-36) cm(6)/s, alpha=1.355 and B=5 39.0 K. The products (Hemu-He)(+) are found in high vibrational states .
