... unity. Figure 2 shows the dependence of T(εr) on εr for different values of β2=Vs/V0. It is seen that T(εr) increases with increasing εr and decreasing β2.This is due to the fact for any value of εr, the width of the energy barrier is larger for higher values of β2 (=Vs/V0 ).

... (a) Consider a beam of kaons (momentum 1.5 GeV) incident on a target of liquid deuterium. Let λ be the K 0 “interaction length”, i.e., the average distance that a K 0 will travel in the deuterium before it interacts according to the above cross section. Similarly, let λ̄ be the K̄ 0 interaction leng ...

The first, an attractive intermolecular force at long distances, helps draw the gas together and the ...
