The second rart of the experiment mu on attempt to obtain in • nerr/ measurements the shelf on the low entry* distribution after slowlnr by on# *11 Ur ram per square centimeter of aluminum that Schmitt And Wachman obtained • In the velocity distribution. Mote that in stopplnr power this foil is About three times ii thick At the thickest uranium oxide Absorber used rrexiouely. Dm next slid* shows *he merry distribution obtained. Note thst there it no evidence for the shelf. Roe If the mechanism for the production of the shelf obtained In tne velocity measurements it that proposed oy Wheeler end just described by Kr. Schmitt, we should Also obtsln such s ehelf in the merry distribution if ve have sufficient resolution. To check the adequacy of our resolution, we took the velocity distribution of the slowed fragments fro* Schmitt*8 data and converted it to an tnerry distribution ualnr Brunton and Hanna11 data for the moat probable rasa corre spend tnr to a riven velocity. This curve is shown In the next slide. Ws then a*ply to this curve the dispersion* necessary to rive us our observed peak-to-valley ratio of $il and note that in so doiny have lost the resolution necessary to allow us to see the step in the curve. Thus our findings tre not contradictory to the mechanism proposed in the previous paper, but we lack the resolution necessary to confirm it. a ........7 "" It is hoped to have the final value of this dispersion by the time the talk Is rlvsn. At the moment we only know that it will lie in th« ranye M Hev full widtn at half maximum. We can then compare it to the value of the dispersion thst Leachman calculated for ionisation measurements (Phjs. Rev. JJ, 17 (1551)) of 6 Mev full width at half maximum. information ■««»
