Final answer:
The actual purpose of the Srb and Horowitz experiment is not elaborated in mainstream scientific literature, but similar significant experiments include the Stern-Gerlach experiment and the Michelson-Morley experiment, which had different objectives in the field of physics.
Step-by-step explanation:
The Srb and Horowitz experiment doesn't have a well-documented purpose in major scientific literature or educational resources in the context of widely recognized physics experiments. Given the mention of the Stern-Gerlach experiment and the Michelson-Morley experiment, it seems there may be some confusion. The purpose of the Stern-Gerlach experiment was to observe the quantization of atomic energy levels, and it was crucial in the development of quantum mechanics.
On the other hand, the purpose of the Michelson-Morley experiment was to detect the presence of the 'ether,' a medium thought to carry light waves, but it instead provided crucial evidence for the theory of relativity by showing that the speed of light is constant in all inertial frames of reference. Kroto, Curl, and Smalley's work, which also doesn't relate to Srb and Horowitz, led to the discovery of fullerenes, a new form of carbon. Without specific context or details on the Srb and Horowitz experiment, it is not feasible to provide the purpose or outcomes of their investigation.
