Hard X-Ray Spectroscopy and Pulsar Phase Analysis of the Bursting X-Ray Pulsar GRO J1744{28 with OSSE
We report OSSE observations of the bursting X-ray pulsar GRO J1744{28 made in December 1995 and January 1996 at hard X-ray energies > 35 keV. The pulse pro le of the persistent (i.e. non-bursting) pulsar emission is t with a sinusoid in the energy range 35{90 keV. Residuals reveal a second harmonic amplitude of 3:0 0:5% of the fundamental. The distribution of time intervals between bursts measu...
متن کاملX-ray and Infrared Enhancement of Anomalous X-ray Pulsar
The long-term ( 1.5 yr) X-ray enhancement and the accompanying infrared enhancement light curves of the anomalous X-ray pulsar 1E 2259+586 following the major bursting epoch can be accounted for by the relaxation of a fallback disk that has been pushed back by a gamma-ray flare. The required burst energy estimated from the results of our model fits is low enough for such a burst to have remaine...

متن کاملSurface Hardness Measurment and Microstructural Characterisation of Steel by X-Ray Diffraction Profile Analysis
An X-ray diffraction line will broaden considerably when steels change into martensitic structure on quenching. The results presented in this paper show that X-ray diffraction technique can be employed for a rapid and nondestructive measurement of hardness of hardened steel. Measurement on various quenched and tempered steels showed that the breadth of its diffraction peak increased with increa...
متن کاملX-ray diffraction peak profile analysis of maraged Fe-Ni-Mn steels
X-ray diffraction peak profile analysis was used to identify changes in the lattice distortions during isothermal aging of Fe-10Ni-7Mn (wt. %) maraging steel. Integral peak breadths were analyzed using classical Williamson-Hall equation taking the elastic anisotropy into account. It was found that substantial lattice distortions rise during precipitation hardening which depend strongly on the s...
