Dynamic polarization in radiation resistant materials

Measurements of spin effects in small cross section processes have shown the need for more radiation resistant polarized target materials. We have examined the dynamic polarization of a number of substances which are known to be highly resistant to the formation of color centers with particular emphasis on toluene. We have also examined the relation between the maximum polarization and characteristic radiation flux constant to obtain a figure of merit for new materials.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/23626/1/0000589.pd

A Rotating Collapsar and Possible Interpretation of the LSD Neutrino Signal from SN 1987A

We consider an improved rotational mechanism of the explosion of a collapsing supernova. We show that this mechanism leads to two-stage collapse with a phase difference of \sim 5 h. Based on this model, we attempt a new interpretation of the events in underground neutrino detectors on February 23, 1987, related to the supernova SN 1987A.Comment: 18 pages, 3 figures, 9 table
