The cross section and polarization for the elastic scattering of protons be carbon and lead at 135 Mev and by carbon at 300 Mev were evaluated in the impulse approximation using the nucleon-nucleon phaseshift sets of Signell- Marshak. Gammel-Thaler, OhnumaFeldman, and Stapp. The detailed calculations were carried out both in ordinary Born approximation and also in terms of a modified Born approximation in which account is taken of the absorption of the elastically scattered nucleon wave within the nucleus. Relativistic effects were estimated and found to be small. The possibility of distinguishing among the various sets of nucleon-nucleon phase shifts is discussed. (auth) The decay of Ti/sup 44/ was studied using scintillation spectrometer, coincidence, and delayed coincidence methods. It was found that Ti/sup 44/ decays by electron capture to the second excited state of Sc/sup 44/. This is followed by a gamma -ray of 79 kev and then a gamma -ray of 70 kev. The 70 kev state is metastable with a half life of 0.18 mu sec. (auth)
