Somebody asked we several days ago regarding the use use mass defect formula. In ZmH do we use the mass of hydrogen always, or use the unified mass of proton?
View this ppt presentation, regarding the issue.
Do we use mass of H or mass of proton?

Electron capture or positron emission?
March 5, 2008Regarding to the latest test you guys took on Nuclear Physics, question 9 states that 64Cu decays into 64Ni isotope by means of positron emission (Schaum’s Outlines’ Applied Physics 4th Edition). But if you pay a visit to webelements at this hyperlink you’ll see that 64Cu decays into 64Ni by means of electron capture. Which one is correct? I don’t know for sure, butI know that whether by positron emission or electron capture, both type of decay would resulted in proton being converted to neutron.

Desktop Publishing (DTP) Tool
March 4, 2008This is very simple to write: there are not many freeware and open source programs for DTP – let alone a portable one. So you can download this and use the program on the fly (after you’ve extracted it, of course). After you’ve done downloaded the file (PortableScribus.exe), just double-click it. Then, you’re ready to go!!!
(Errr…go where?)
