Coherent control techniques are computationally applied to cold (1 mK<T<1 K) and ultracold (T<1 muK) Ne*(3s,3P2)+Ar(1S0) collisions. We show that by using various initial superpositions of the Ne*(3s,3P2) M={-2,-1,0,1,2} Zeeman sublevels it is possible to reduce the Penning ionization and associative ionization cross sections by as much as 4 orders of magnitude. It is also possible to drastically change the ratio of these two processes. The results are based on combining, within the "rotating… Expand
