In retherford's scartering experiment which of the following does not happen ?

Options

A. Most of the `alpha-rays` pass through without deflection
B. A few `alpha`-particles pass through the nucleus
C. A few a- pazrticle are defleted back
D. a- particle going near the nucleus are slighty defected

Explanation

To solve the question regarding Rutherford's scattering experiment, we need to analyze the options provided and determine which one does not occur according to the findings of the experiment.

### Step-by-Step Solution:

1. **Understanding Rutherford's Experiment**:
- Rutherford conducted an experiment where alpha particles were directed at a thin gold foil. The behavior of these particles was observed to understand the structure of the atom.

2. **Analyzing the Options**:
- **Option 1**: Most of the alpha rays pass through without deflection.
- This is true. Rutherford found that most alpha particles passed through the foil without any deflection, indicating that atoms are mostly empty space.

- **Option 2**: A few alpha particles pass through the nucleus.
- This is false. No alpha particles were observed to pass through the nucleus. Instead, they were either deflected or passed through the empty space around the nucleus.

- **Option 3**: A few alpha particles are deflected back.
- This is true. A small number of alpha particles were deflected back, indicating the presence of a dense, positively charged nucleus.

- **Option 4**: Alpha particles going near the nucleus are slightly deflected.
- This is also true. Alpha particles that came close to the nucleus experienced slight deflections due to the positive charge of the nucleus.

3. **Conclusion**:
- The only statement that does not happen according to Rutherford's experiment is **Option 2**: A few alpha particles pass through the nucleus.

### Final Answer:
The correct answer is **Option 2**: A few alpha particles pass through the nucleus.
