The aim is to observe in the same experiment both the 511 keV annihilation line and the W Kα. Rönt

Representations: From Words to Images theoretical work on heavy and super-heavy atoms (4). With the increasing performance of Ge(Li) spectrometers the errors of several calibration lines became about as large as those of the measurement. However one would wish that in practically all cases the uncertainties of the standards were much

Multi-criteria Fuzzy Portfolio Optimization,e proton binding energies, derived from our measurements and those given in the 1964 mass table /1/ and also in the 1971 mass table /2/. Therefore, we made a systematic investigation in order to obtain more accurate values. The reactions studied were .Sr(p,r).Y, .Y(P,r).Zr, .Zr(p,r).Nb and .Mo(p,r).

The deduced calibration parameters relate the proton beam energies to the field strength of the 90. magnetic analyzer. However, these parameters can change sig

Furthermore, G. is related through Cabibbo theory to the corres

Many short-lived radioactivities had been investigated previously using the 3.5-MeV Van de Graaff at Brookhaven including a number of nuclides formed by tri
