125 The 2 has been produced in the reaction
K + p → Kº + K+ + S¯
What is the minimum momentum of the K in the Laboratory for this reac-
tion to proceed assuming that the target proton is at rest in the laboratory?
Assume that a 2 is produced in the above reaction with this momentum
of K. What is the probability that will travel 3 cm in the Lab before
interacting. The rest
decaying? You may ignore any likelihood of the
energies of K+, K¯, Kº, P, S¯ are 494, 494, 498, 938, 1,675 MeV, respec-
tively. Lifetime of S2 = 1.3 × 10-1⁰ s.

T12 = 20.3 min.
The maximum energy of the emitted positrons is 0.960 MeV. (a)
Show that the disintegration energy Q for this process is given by
Q = (mc - mg - 2m.)c²,
%3!
where mc and mg are the atomic masses of "C and "B, re-
spectively, and m, is the mass of a positron. (b) Given the mass val-
ues mc = 11.011 434 u, mg = 11.009 305 u, and mą = 0.000 548 6 u,
calculate Q and compare it with the maximum energy of the emit-
ted positron given above. (Hint: Let mc and mg be the nuclear
masses and then add in enough electrons to use the atomic
masses.)
