Studies On The Decay Of 241Am
(
Qatar University
, 1989 , Article)
The gamma-spectrum of '"Np following the <X -decay of "'Am has been studied using hyper pure Ge-detector and Ge-NaI(Tl) coincidence spectrometer. Some recently reported weak gamma transitions are confirmed, besides two ...
Annealing Behaviour, Tcr Values And Defect Density For "Cold-Condensed" Silver Films
(
Qatar University
, 1990 , Article)
Thin silver films were deposited under vacuum of 10^ -6 Torr by thermal evaporation onto cooled glass substrates kept at low temperatures. Pure argon gas prevailed as residual gas. Annealing behaviour of the electrical ...
Variation Of The Electrical Properties Of Manganese Thin Films With Deposition Conditions
(
Qatar University
, 1989 , Article)
The behaviour of the electrical properties of manganese thin films of different thickness (240 - 1500 A) evaporated under different deposition conditions was studied. The effect of the rate of evaporation (1-7 A/s), the ...
