Let f be the fraction of the detected alpha particles that were deflected through large angles (greater than 90 degrees). Would careful measurement of f would allow Rutherford to estimate the size of the nucleus of the gold atoms?
Homework Answers
Yes, by careful measurement of fraction of particles scattered at greater angle (more than 90) would give size of nucleus. Since the positive charge and the mass of gold atom are concentrated in a small fraction of the total volume and then deriving mathematical equations for the scattering would predict that the number of -particles scattered through a given angle should be proportional to the thickness of the foil and the square of the charge on the nucleus,

In Rutherford scattering of alpha particles by a gold foil, large deflections can occasionally be observed because: a) a single alpha particle can be scattered many times in encounters with many atoms. b) the alpha particle can be deflected by the many atomic electrons of the gold. c) the wave nature of the alpha particles causes interference effects. d) none of the above.

In the Rutherford Gold Foil experiment, alpha particles (with a charge of 2e and a mass of 6.645×10-27 kg) were shot directly at a thin sheet of gold with a speed of 1.017×107 m/s from very far away. They found that most of the time the alpha particles traveled straight through the thin sheet, but sometimes they would bounce directly back. The alpha particle would only bounce back when its path was aimed directly at a gold nucleus (otherwise it...

Carlsberg in Emerging Markets A breeze of optimism blew through the office of Carlsberg A/S’s CEO, Jørgen Buhl Rasmussen. After finally gaining 100 percent control over the giant Russian brewery Baltic Beverages Holding (BBH), and with the investments in Western China beginning to bear fruit, the newly appointed CEO was confident that the Danish brewing company’s intensified focus on emerging markets would pay off. The company was counting on tapping the massive potential in emerging markets in order to achieve...
