Final answer:
To identify the particle, one must apply the de Broglie wavelength formula in conjunction with the given velocity to calculate the particle's mass, then compare it to known particle masses.
Step-by-step explanation:
The question relates to the application of the de Broglie wavelength concept to identify a particle given its wavelength and velocity. The de Broglie formula is λ = h / p, where λ is the wavelength, h is Planck's constant, and p is the momentum of the particle. Given that we know the wavelength (λ = 33.25 fm) and the particle's velocity (1% of the speed of light is 0.01 × 2.998 × 10⁸ m/s), we can find the particle's momentum (p = mv) and then its mass (m = p / v). Comparing the computed mass with known particle masses should reveal the identity of the particle.
