In Rutherford's experiment , scattering of more than `1^@` was observed in

Options

A. 14% of the incident `alpha`-particle
B. about 0.14% of the incident `alpha`-particles
C. about 1.4% of the incident `alpha`-particles
D. about 0.014% of the incident `alpha`-particles

Answer

To solve the question regarding the scattering of alpha particles in Rutherford's experiment, we will follow these steps:

### Step-by-Step Solution:

1. **Understanding Rutherford's Experiment**:
- In 1911, Ernest Rutherford conducted an experiment where he directed alpha particles at a thin gold foil to study the structure of the atom. The experiment aimed to observe how these particles scattered when they encountered the atomic nucleus.

2. **Observations from the Experiment**:
- Most of the alpha particles passed straight through the foil without any deflection.
- A small fraction of the particles were deflected at small angles.
- A very tiny percentage of alpha particles (about 1 in 8000) were reflected back, indicating the presence of a dense nucleus.

3. **Quantifying the Scattering**:
- The question specifically asks about the scattering of more than 1 degree. In the experiment, it was found that approximately 0.14% of the incident alpha particles were scattered at angles greater than 1 degree.

4. **Conclusion**:
- Therefore, the answer to the question is that in Rutherford's experiment, scattering of more than 1 degree was observed in approximately **0.14%** of the incident alpha particles.

### Final Answer:
In Rutherford's experiment, scattering of more than 1 degree was observed in approximately **0.14%** of the incident alpha particles.
