THE WORLD-MOVER _Feature Novel by GEORGE O. SMITH_ _Les Ackerman, unbelievably alive after a nuclear explosion, finds himself sought after by the denizens of three possible worlds, all contending that Ackerman alone can adjust the incredible situation he has created. Only Les doesn't know what he's done!_ [Transcriber's Note: This etext was produced from Future combined with Science Fiction Stories November 1950. Extensive research did not uncover any evidence that the U.S. copyright on this publication was renewed.] To the present sitting, there were three hundred thousand words in the report on the new transuranic element that Les Ackerman was studying. This took months of painstaking work, but Ackerman viewed his results with satisfaction. To date, the report covered about all that was to be known regarding the physical and chemical properties of this new element; there remained only the nuclear properties to investigate. Nuclear properties were always left to last. Nuclear bombardment defiled the element and rendered it unsuitable for the undestructive chemical analysis and physical investigations. So Les Ackerman closed his notebook with a slam and checked the refrigerator. The deuterium-ice--frozen heavy water--for the cyclotron target was in fine shape. He could start at once. He took both the ice-target and the sample to the big, enclosed room and inserted them in the proper places in the cyclotron set-up. Then he fired up the big cyclotron, and high-energy deuterons bombarded the deuterium-ice target, releasing free neutrons that in turn bombarded the sample. That was to be his last job for the night; the registering counters would record the radioactivity while he slept, and in the morning the sample would probably be 'cold' enough to handle. He consulted his prospectus in the notebook and checked the bombardment-time for this first nuclear test. One half hour. At the end of one half hour, Ackerman could turn off the cyc and go to bed. The automatic counters would quietly record the diminishing activity of the 'hot' sample. The click of the counting-rate meter sounded. The first atoms of the sample were being attacked properly. Ackerman nodded to himself, there in the operating chamber, separated from the real activity by solid yards of concrete, water, and paraffin. Unluckily, Ackerman could not be in the cyc chamber itself to watch. As it was, it would have been no more dangerous for Les to stand in the radioactivity-laden cyclotron room than it was for him here in what all cyclotron mechanics considered more than safe from harm.
