Since the original observation that the surfaces of materials undergo radiation damage in the electron microscope similar to that observed by more conventional surface science techniques there has been substantial interest in understanding these phenomena in more detail; for a review see. For instance, surface damage in a microscope mimics damage in the space environment due to the solar wind and electron beam lithographic operations.However, purely qualitative experiments that have been done in the past are inadequate. In addition, many experiments performed in conventional microscopes may be inaccurate. What is needed is careful quantitative analysis including comparisons of the behavior in UHV versus that in a conventional microscope. In this paper we will present results of quantitative analysis which clearly demonstrate that the phenomena of importance are diffusion controlled; more detailed presentations of the data have been published elsewhere.As an illustration of the results, Figure 1 shows a plot of the shrinkage of a single, roughly spherical particle of WO3 versus time (dose) driven by oxygen desorption from the surface.

<p class="JurnalASSETSABSTRAK">ABSTRAK</p><p>Pengampunan pajak telah dilakukan berulang kali di Indonesia yaitu 1964, 1989, 2008 dan 2016. Penelitian ini menguji apakah ada perbedaan kepatuhan pajak antara yang mengetahui pengampunan pajak berulang serta merasakan kepastian penegakan hukum dan yang tidak. Penelitian ini menggunakan  quasi eksperimen faktorial 2 x 2 antarsubyek dengan mahasiswa akuntansi di FEB yang sedang mengambil matakuliah manajemen pajak sebagai partisipan. Hasil dari penelitian ini adalah terdapat pengaruh antara pengetahuan tentang pengampunan pajak berulang maupun kepastian penegakan hukum terhadap kepatuhan pajak. Hasil dari pengujian interaksi yang diperoleh adalah ketika wajib pajak tidak mengetahui adanya pengampunan pajak yang berulang dan merasakan kepastian penegakan hukum yang tinggi akan menghasilkan kepatuhan yang paling tinggi. Sebaliknya ketika wajib pajak mengetahui adanya pengampunan pajak yang berulang dan tidak merasakan kepastian penegakan hukum yang tinggi akan menghasilkan kepatuhan yang rendah.<em></em></p><p class="JurnalASSETSABSTRAK"><em>ABSTRACT</em></p><p><em>Tax amnesty has been repeadly implemented in Indonesia namely 1964,1989, 2008 and 2016.The purpose of the study is to examine is there any tax compliance differences between those who perceive recurring tax amnesty and feel legal certainty and to those who do not. This quasi experiment design was consisted of 2x2 between subject factorial design, with Bachelor’s Degree of Accountancy at FEB UKSW who took Taxation Management as participants. The result shown that there is influence between recurring tax amnesty knowledge and legal certainty in the tax compliance. The result of the interaction testing shown that when taxpayer are not aware of any recurring tax amnesty and feel the high legal certainty will result high compliance. Conversely, when taxpayers know that there is recurring tax amnesty and do not sense a high level certainty, it would result a low tax compliance.<br /></em></p>
