- Schrodinger's cat is one of the most common subjects in modern physics for cartoonists. Here's what Erwin Schrodinger said about his famous thought experiment, "One can even set up quite ridiculous cases. A cat is penned up in a steel chamber, along with the following diabolical device (which must be secured against direct interference by the cat): In a Geiger counter, there is a tiny bit of radioactive substance, so small that perhaps in the course of one hour, one of the atoms decays, but also, with equal probability, perhaps none; if it happens, the counter tube discharges, and through a relay releases a hammer which shatters a small flask of hydrocyanic acid. If one has left this entire system to itself for an hour, one would say that the cat still lives if, meanwhile, no atom has decayed. The first atomic decay would have poisoned it. The function of the entire system would express this by having in it the living and dead cat (pardon the expression) mixed or smeared out in equal…FIND F(S) BY THE FOLLOWING PROBLEM, STEP BY STEP i) L{e2-t A(t- 2)}A neutron collides elastically with an initially stationary deuteron.

- What is β for a particle with (a) K = 5.29 E0 and (b) E = 5.29 E0?Consider a proton confined within typical nuclear dimensions of 5×10^(−15) m. Estimate the minimum kinetic energy of the proton. Repeat this calculation for an electron confined within typical nuclear dimensions. Comment briefly on the physical significance of your results, given that the nuclear binding energy for a proton is typically in the range 1−10 MeV
