“…The measured results are compared with theoretical values based on MF, MFASF, and SM approach formalisms. The present work reports experimental data on elastic scattering cross sections at the above‐mentioned photon energies for the first time and can be considered an extension of our recently published results …”

The differential elastic scattering cross sections were measured for 25.2 (Sn‐Kα), 28.5 (Sn‐Kβ1,3), 37.4 (Nd‐Kα1), 36.8 (Nd‐Kα2), and 42.2 (Nd‐Kα1,3) keV X‐ray photons at 139° scattering angle in elements with 22 ≤ Z ≤ 83. The measurement was done in reflection mode experimental setup involving 50Sn/60Nd secondary targets excited with 241Am radioisotope. The scattered X‐ray photons were detected using a high‐resolution low energy germanium detector (horizontal configuration, FWHM = 300 eV at 59.5 keV) coupled with computerized multichannel analyzer. The intensity of X‐ray photons along with geometrical factors were calculated from the theoretical knowledge of K X‐ray fluorescence cross sections and measured K X‐ray yields from excited targets. The measured values of differential cross sections were compared with the theoretical available values based on form factor and second‐order S‐matrix (SM) approaches. The experimental values of cross sections exhibit a large deviation from modified form (MF) values for the elements with BK/Ein ≈1, where BK is the K‐shell binding energy of electrons and Ein is the energy of incident photon. These deviations in experiment results were smooth out by the inclusion of anomalous scattering factors (ASFs) to the MF values. The measured elastic cross sections were found to be ~7% lower than MFASF values and agree with SM values for all elements under investigation.

“…These prospects are adopted as component of the critique in the paper [9]. Beerendra Pandey constitutes a comparative study of two Indian English partition novels, which deals with doctrine of non-violence put forward by Mahatma Gandhi, which also analyses the social confrontation between two cultures and two religions as well [10]. Uma Parameswaran systematically elucidates the account of a woman torn between family responsibility, the aspiration for education, and illicit love relationship.…”

Purpose: This paper analyses the traumatic aspects prevalent in select Partition novels in Indian English literature. An inquisition of how these writers delineate the traumatic condition of the women characters in their partition narratives and the manner in which they interweave memories, pangs, sufferings, thoughts, riots and experiences with their past and the sense of trauma experienced by them. This study will be examined in detail on the effects of disaster or catastrophe on the inner psyche of characters and consciousness that dismantles the identity of an individual. Design/Methodology/Approach: It will be a qualitative analysis including close reading, interpreting, comparing, and contrasting the primary sources chosen for the study. Critical essays on trauma theory and partition novels and books on partition narratives and trauma theory will also be incorporated to conduct the research. Findings/Results: The outcome of the partition of the Indian subcontinent will ever be an issue of national prominence. The Partition event has enhanced many problems and inquiries about citizenship, national identity and traumatic experiences of the people. However, it is often examined, it still postulates from us an upholding pursuit for many essential answers. Originality/Value: The literature of partition sheds light on the then subsisting doctrines and its shift due to partition, which renders in new discernment about the social, historical and psychological experiences during that time. Partition induced a great agitation in history that interwoven with the miseries and trauma. These novels investigate how people outlived the holocaust, how they survived grappled with the trauma and renew their lives. These writers have perceived the pathos of people and the human agonies that preceded and accompanied partition. These novels demonstrate the impressions of abstruse nostalgia of the survived and deposed and intense pain of missing their motherland forever. Paper Type: Analytical research study.

The polarization dependence of the cross sections of two-photon transitions including X-ray scattering was analyzed. We developed the regular approach to the derivation of the polarization parameters of photoprocesses. Our approach is based on the tensor representation of the photon density matrix, which is written in terms of the unit vectors directed along the major axis of the polarization ellipse (ϵ^) and the photon propagation (k^). Explicit expressions for the product of two photon density matrices were derived. As an example, the parametrization of the polarization dependence of the X-ray scattering by closed-shell atoms is given both in terms of (i) scalar products of photon vectors ϵ^1,2, k^1,2 and (ii) X-ray Stokes parameters. We discuss the applicability of the atomic scattering for the measurement of the polarization of X-rays.
